Although cryptocurrency is becoming more and more common today, not everyone loves the idea of using or investing in this financial medium. Regardless of how advanced technology is, a lot of people would still opt to pay for their transactions using cold hard cash. Aside from keeping up with the times, using cryptocurrency as your financial medium allows you to enjoy the following benefits:.

The currencies joining Bitcoin are called altcoins. Altcoins are said to be a modified or improved versions of Bitcoin. Investing in cryptocurrency starts with you having to first purchase Bitcoin. You will be able to do this by creating an account with an exchange. It is important because the exchange acts as a medium where buyers and sellers trade coins as per the respective currency selected by the buyer.

Also, the coins can then be transferred to a different exchange. Each exchange has its own guidelines and rules. Be sure you are through with them before trading.

Manage and grow your wealth effortlessly. Millennial investors are looking beyond traditional assets such as stocks, bonds, and real estate to find opportunities to make their fortune. Many young people are launching their own startups, investing in startups, and joining the gig economy among other things.

Interestingly, cryptocurrencies such as Bitcoin, Litecoin and Ripple are gradually rising in prominence as an interesting way to make your fortune. Cryptocurrencies fundamentally refers to virtual currencies that are cryptographically encrypted to prevent their duplication while the records of their transfer of value is stored on a blockchain.

For a beginner trader or investor, it might be somewhat hard to make heads and tail of the similarities and differences if any between coins, tokens, and altcoins. The industry is not making much effort to differentiate between the different types of cryptocurrencies. For instance, you can store coins, tokens, and altcoin together in multi-cryptocurrency wallets and many new cryptocurrency traders erroneously think that coins, tokens and altcoin all mean the same thing.

This piece provides concise information that could help you identify and differentiate the different classes of cryptocurrencies. A cryptocurrency coin is primarily designed to facilitate the transactional transfer of value. Bitcoin and Monero are two examples of cryptocurrency coins in the market. Did you know that those currently or planning to provide services surrounding cryptocurrency may need a money transmitter license based on state or federal rules?

These coins are regulated and are the real deal. Cryptocurrency coins can be further categorized into groups based on their use cases. For instance:. Value coins such as Bitcoin and DigixDAO are transitioning from being used for transactional purposes to become a blockchain-backed store of wealth. Bitcoin is the oldest cryptocurrency in the market and its blockchain has never been hacked in the last 9 years of its existence.

Stable coils such as the Tether could also qualify as value coins because their value is pegged against a fiat currency. Transactional coins tend to have near-instant settlement and practically negligible network fees. Privacy coins such as Monero are created to offer users with the original promise of privacy and anonymity that cryptocurrencies could offer over fiat currencies.

People who want a layer of anonymity on how their cryptocurrency holdings would love Monero for its stealth addresses and ring signatures. Cryptocurrency tokens are primarily built to serve utility or security purposed on a platform built on a blockchain such as Ethereum or Stellar. While Ethereum itself is a platform for building and hosting decentralized applications, the cryptocurrencies used on such applications are usually referred to as tokens.

All cryptocurrencies used on ERC platforms are tokens. Utility tokens are designed to provide access or for transactions within a network or platform. Tokens such as Binance Coin and VeChain are used to access network features such as discounts on Binance Exchange and to track orders on VeChain respectively. People who hold security tokens can vote, weigh on decisions, and expect dividends on their part ownership of a blockchain venture. Other types of tokens include network tokens which are designed to incentivize people to the growth and development of a blockchain.

A hybrid token could be a mix of utility, network, security token. An altcoin is fundamentally a cryptocurrency that started with the same source code that was used to create Bitcoin—but with certain code modifications that makes it different from Bitcoin. Altcoins include Dash, Bitcoin Cash and other future forks of Bitcoin. Even digital money requires a wallet.

You store your cryptocurrencies in a wallet. Also, you can purchase cryptocurrency, buy into an initial coin offering ICO , or execute smart-contracts using the wallet. Every wallet has a public address and a private address. The public address is the address where you receive funds from people. Never share your password. Otherwise, you might lose all the money in your wallet. Blockchain , regarding cryptocurrency, deals with the way in which data is structured.

Also, it records all transactions to keep track of who had paid what and how much. Moreover, it makes payments faster and more secure. This process altogether throws light on Cryptocurrency Mining, which is an interesting concept again. Crypto miners verify the transactions recorded in the blockchain and write them into a general public ledger.

Initially, the seller and buyer need to sign an agreement. The transactions are to be held only after checking whether the requirements are met or not. Recent years have seen an immense increase in awareness about cryptocurrencies, which are based on the invention namely blockchain technology. And with the increased awareness, it can easily be said that more and more people are now investing in bitcoins and cryptocurrency in order to make some profit and have assets for themselves. While cryptocurrency can be bought through online exchange sites , there are various cryptocurrency wallets which people can use to keep their cryptocurrency safe.

Bitcoin hardware wallets are considered more secure than other wallets. These cryptocurrency wallets come in two categories, either as a connected device, which performs various tasks of any other wallet by helping you select which deals you wish to trade in, or the other option is a disconnected device. Other than these hardware mining bitcoin, other cryptocurrencies such as LiteCoin, Dash, Ethereum etc. Ledger Nano S : One of the more affordable hardware wallets, available in the market which enables storing multi-currencies, is made as a smart card device.

It has free updates, and its user interface is compatible with all software, making it a hassle-free device. Trezor : It is another form of a cryptocurrency wallet that can be used to store bitcoins and make easy transactions. The user can validate transactions through the device, merely by clicking the correct buttons. It is designed in a manner that the user will have to facilitate each and every transaction, as all the requests would go through authorization.

Additional feature of KeepKey is that is can easily be integrated with any other wallet software, by generating private keys and storing them. Every day, new people are discovering the benefits of bitcoin and cryptocurrency. Many have purchased their very first digital asset from exchanges such as Circle Invest or Coinbase. However, only a few will have learned how to keep their private keys secure so that they can really call themselves the owner of those precious coins.

This is a fact that will become an increasingly important one to know as bitcoin grows in popularity. The digital currency is being used more and more widely in a number of industries. A private key is a secret alphanumeric code mathematically paired with your public key- the alphanumeric address where you receive payments. So inflation is built into the system. If this were a bitcoin transaction, enough miners need to approve that this transaction is valid.

So even if a few miners are not trustworthy, the bulk of them will be, and we can trust that the transaction between Joe and me is legit. As well as have high security and avoid forgery. This reason is sometimes the basis for ICO rating. This was also originally the entire reason for the origin of money as opposed to a barter system which requires an exponential number of negotiations to determine the correct exchange rates between each object. Crypto is just the next step after that.

For bitcoin, the cost might be zero depending on your exchange , and miners get paid by getting more bitcoin depending on the computation power used to verify these transactions. One more good: Blockchains are incredibly resilient. A blockchain can survive unaffected as long as just one stays alive. With bitcoin, nodes are running all over the world. The power is distributed. To kill it, you have to erad- icate it completely, globally, totally, without fail, all at once.

This is very hard to do. The bad: Miners approve transactions one block at a time. A block is a set of transactions. Blockchains are slow. Blockchains are slow because blockchains are extremely inefficient — especially compared to Visa, MasterCard or PayPal. Decentralization and censorship-resistance. Blockchains are inefficient. That software layer involves humans humans are bad , which invites good players and bad players to be involved hence, the Mt.

Blockchains are very hard to scale. In exchange for security, trust, fewer middlemen and avoidance of gov- ernments and boundaries, society pays in computational costs, storage the same blockchain stored on millions of computers is a waste and slower transaction speeds. And the software layer above the blockchain needs to evolve, which it is the same way internet software evolved post This is the ENTIRE reason multiple currencies exist and why there is a huge need to keep things simple and not get caught up in the hype.

Coins can be divided into two types: A They keep the same rough philosophy of bitcoin security, limit on minting of new coins, elimination of middlemen and boundaries, validations of trades, impossible to forge. Unfortunately, the only way to know this is to read the code, and there are hundreds of thousands of people using these currencies right now, unaware of the trap they are in.

So… why more than one? Or you can just copy and paste from other currencies and add features you like. Sure, most of them will be useless. I think there will be many winners. Data-based currency is an important evolution. And the children inherit traits from the parents. There are many valid currencies. Because dollars are in America and euros work in Europe.

This is based on the arbitrary and fictional geographic borders that were set up through human-led trade agreements, wars, etc. With cryptocurrencies, there are no geographic borders. Bitcoin and ether, for instance, work just as well in every single part of the world. For instance, upon writing this book, bitcoin is very slow to validate a transaction. I found a possi- ble solution. Another problem: privacy. Bitcoin transactions have privacy. Legitimate problems in certain cases and a lack of geographic borders are what create new cryptocurrencies.

B A data-based currency can have some functionality. Your data sits on servers owned by Google or Dropbox. There is a potential for human error and privacy loss. This is a lot for this introduction. I will describe the size of the opportunity in a future issue.

Because in any eupho- ria, criminals are created. We saw it with internet stocks in ; we saw it with hedge funds in the s; we saw it with mort- gage-backed securities in and now we are going to see it in cryptocurrencies within the next year or so. But the industry itself will boom. This was a lot for one issue. And cryptocurrencies are a very compli- cated subject. Like I said, to actually know for sure if a cryptocurrency is legitimate or not, the only way is to read the actual software that created it.

The good news is that, unlike the dollar, the software is available. Geographic boundaries create new currencies. But geographic boundaries are man- made and artificial, and many possible untrustworthy middlemen are required.

The ones I recommend you take a look at are: A. Coinbase — the most mainstream option. Certainly the most established. Buying and selling is easy and your bitcoins are insured. ICOfuffer — Another great choice. Kraken is known for its security, support and low fees. Signing up and getting started is simple. If you can use PayPal or online banking, you can figure these out fairly quickly. Cryptocurrencies are the first form of money you can store in your brain.

Let me unpack what I mean by that. Your private key unlocks your funds. The exchange does. One great thing about cryptocurrencies is you can become your own banker — so keeping your crypto on an exchange defeats this purpose. They have one vector of attack and, if hit hard enough, they come crashing down.

So how do you secure your coins private keys? Store them in your safe, hidden compartment or in a fake can of hairspray buried in your backyard [somewhat difficult, highly secure] D. Well, sorry to send you off, but the easiest method, as usual, is to Google it. The security of your coins is as strong as the security of your device. If you want maximum security, I suggest you either: A.

Secure your money in your brain B. Secure your money in your safe C. Most recommended Secure it in a cold-storage wallet device although this choice is limited to a few coins. Remember: The reason crypto exists is so you can better control your own money.

How to create a brain or paper wallet Cryptocurrencies are the first form of money you can store in your brain. There are many ways to do this. This process can get extremely compli- cated. First step: Go to WarpWallet. You should be shown the same page. And put an email in the email box. I want to reiterate the importance of a strong passphrase. Meaning, given enough time, hackers could figure it out by testing out every possible combination of characters. Strong passwords are meant to make this process as cost-prohibitive and time-intensive as possible.

The purpose of a brain wallet is not having a paper trail. Write it in your journal, coded within every sev- enth word. Write it in a book by circling the letters on every third page. Get creative. Or just write it down and keep it in a VERY safe place. If you go the paper wallet route, you have two choices: 1. Your QR code will make it easier to spend your funds in the future. More on that in a moment.

One inside your home. One outside your home. And another elsewhere. You decide. You know best. Important: The privacy risk in other people knowing your public key is they can look up how much money you have on that particular address. Something to keep in mind. Destroy all evidence before you log back in. Copy your public bitcoin address and go to your chosen exchange Coin- base, Kraken or whatever you choose. Pro-tip: Always send a tiny bit on your first go to ANY address to test it out. If your computer is compro- mised, hackers can replace your address with theirs in your clipboard.

Access and spend your bitcoins If you chose the brainwallet option, simply open up your Warp Wallet again preferably offline and enter your passphrase and email. Grab your private key. If you chose your paper wallet, you already have your private key. Get it. Claiming the funds requires specific software. There are varying degrees of safety when doing this. The first is a way to put ALL of your funds on a web wallet.

The second is a way to do a partial spend in which the wallet de- stroys your private key when the transaction is over, keeping the remaining funds secure. An email address is optional but helpful for re- covering your account should the need arise. Pro tip: Use a password manager like LastPass to create a character password with uppercase and lowercase letters, numbers and special characters.

Click it. Save your Wallet ID in a safe place. Wallet ID and Password. Be sure to check your email and verify that. And then, if you wish, enable two-factor authentication using your mobile number. Meaning, before you log in, you must verify a code sent to your phone. Not foolproof, but better than not doing it.

If you happen to lose your password, you can use these words in this order to recover your funds. Use it. Write all of them down in a safe place. DO NOT store them on your computer. Select your destination address 5. Select the amount 6. Press the blue currency tag at the top to toggle currency 7. After spending, the private key in memory is destroyed so the paper private key remains secure. Simply get a cold storage device. The ones I recommend you check out are Trezor or a Ledger wallets.

Unfortunately, they are currently limited to a few coins. Both use state-of-the-art cryptographic technology to hold your pri- vate keys offline — even when the device is plugged into your computer. But please. Do your own due diligence. Cryptocurrencies have a purpose. Politically, they are built to help you gain independence of your life from institutional whim. You can cut out the middlemen. Someone in Brazil can pay someone in Switzerland without having to get permission from someone or something in New York City.

An evo- lution, as mentioned, theism to humanism to data-ism. Bitcoin is the first sketch. And I believe ethereum will lead the way. With this code, anyone can create a new cryptocurrency and set the initial supply in minutes. Everyone on the network must recognize it is real. So while bitcoin is focused on being a store of value and a currency, ethereum is focused on smart contracts and the construction of decentral- ized applications on the blockchain. Law school — Property and contract law are the fundamental building blocks of commercial society.

Our contracts become that fly in the amber I mentioned earlier. Once set into the blockchain, they become immutable and unstoppa- ble. Moreover, data and programs are auditable by anyone. This means… A. Anyone can audit the blockchain and prove you did what you said you did. Way before bitcoin. Way before ethereum. So the vending machine in contract law terms, it verifies performance. You put in your quarter and it verifies you put in the quarter through its me- chanical [slot]. It has logic in it that says OK, you put in a quarter, the soda costs a dime.

But smart contracts can go much further than that. The company can release one colored coin to represent each car and then configure the car to turn on only if it receives a message signed with the private key that currently owns the colored coin.

It can then release a smartphone app that anyone can use to broadcast a message signed with their private key and put up the colored coins on a trading platform. Decentralized apps dapps could eat the world, run from the ethereum network.

Meaning, no middlemen to speak of. Imagine, too, YouTube and Facebook becoming P2P, where the users get paid to show ads rather than a central commander sucking out all the value. Digital plantations. The more applications built on the ethereum network, the more valu- able ethereum becomes. And it just takes one killer dapp to make the ethereum network worth it.

But I think there will be many. My quick answer to which cryptocurrencies people should avoid is ALL of them. In every boom market, there are always going to be scam- mers. It happened in the dot-com boom. Companies showing no profit went public — just to make the founders rich.

It happened in the housing boom, in which a lot of scammers got rich. They are just land mines waiting for some fool to step on them. The thing is people hear about all of the great things cryptocurrencies can do and they get starry-eyed.

Charlatans then rush in in droves. The value can always be found in simplicity. You can invest in crypto from your regular old Fidelity account. First, though, let me give you the broad overview of how I view cryp- to investing. You might ask: How do we estimate value in crypto? Plus, it solves a big problem — hunger. To build a proper crypto portfolio, you must be able to determine which coins follow the pure cryptocurrency philosophy.

These legit coins belong in a diversified portfolio of cryptocurrencies. See previous chapters for the more technical descriptions of these portfolio-worthy coins. TRADES: Because of the great volatility as the world tries to determine intrinsic value for this brand new asset class, we can take advantage when volatility creates a big gap between current price and our estimation of value for each legit currency in the portfolio.

Why does volatility create opportunity? Volatility is a mainstay of the cryptocurrency world. And it presents plenty of opportunities for skilled traders to make money. Some people got rich on gold. But blue jeans thrived. The same thing will happen here.

Chip companies, financial companies, retail companies, security com- panies and companies in every industry will have winners and losers in the crypto space. The winners will go up many thousands of percent, regardless of what happens in the economy. In fact, a recession might even be good for these companies as people get nervous about their currency. But what if this is all theory and cryptocurrencies take decades to get accepted by the masses?

No problem. Games require high-speed graphics and the chips to handle that. Earlier I mentioned that in a cryptocurrency transaction, there are computers that specialize in validating transactions. Some companies have thousands and thousands of computers set aside JUST to validate transactions. Miners benefit when their chips are fast. NVDA makes the chips that are most popular with miners right now. So regardless of the economy, NVDA will sell more chips each year than the year before as the rise of cryptocurrencies continues on pace.

Good things are happening with this company regardless. You see, every boom follows a sequence of three stages… First, only early enthusiasts are courageous enough to invest in the new trend. Finally, the public joins the party, triggering a massive explosion in price. If you know how to use this road map, you could make an absolute fortune. And to help you understand how this sequence works… Let me show you what happened during the s boom in tech stocks.

That was Stage 1 of the boom! That was Stage 2 of the boom. But the public was still not participating. And regular folks started to wonder: Why not me? The result? Stocks went straight up. In alone, the stock market doubled. The Housing Boom U. This script is so reliable that it 35 goes back centuries… Just look what happened with 30 shares of the South Sea Co.

And in each one of those booms, people who knew how to use this 3 script walked away with a fortune. Much like the internet in , most people dismissed it as a useless technology. Only early enthusiasts invested in bitcoin… That was Stage 1 of the boom.

And what started in has only intensified in Once all these 70 funds get set up, billions of new capital will flow into these cryptocurrencies… Helping push them even higher. Imagine what will happen if some of those trillions start moving into cryptos!

Remember, this is all part of Stage 2 of my three-step script. Simply put, when these guys invest in something new, you should pay close attention. How do I know that? Mark Cuban is planning to get involved Google is investing in it… and so is billionaire Richard Branson. I declined their offer. Those are the things I love to do. And no amount of money in the world can make me give it all up.

To this date, fewer than one in 10, people have invested in bitcoin. Just ask your friends, spouse and neighbors what they think of ethere- um, litecoin and monero. Not yet! Remember, the biggest gains in any bull market throughout history only happen when the public joins the trend. With cryptocurrencies minting new millionaires seemingly every day… This epic boom is starting to grab some headlines. Simply put, this event will trigger a buying frenzy… And help mint a new round of crypto millionaires.

You see, big tech companies like Microsoft and Overstock are already accepting bitcoin as a form of payment. And they could make an announcement anytime. Only those who get in early will get a good deal. Most people will be left out. Get ahead of the massive buying frenzy that will push cryptocurrencies straight up.

Humans would decide war. Whoever had more bullets and people on the ground would win the war. But where is the war now? I will tell you. The war is being fought with data. Was the election manipulated? Were emails hacked? Of course they were. And that will never stop. The data wars are in full force. The people reading about them in the newspapers are only reading the rough draft of history.

History will eventually be written by the greatest hackers in these wars. The winners. Money is following this evolutionary path as well. Take out a one dollar bill. If you can trust God, you can trust this dollar bill. But even then, trust our Founding Father George Washington and the signature of the secretary of the Treasury. This is a contract! But you have to trust humans to make money in its current form work. And as we will see, humans can make mistakes. And mistakes about mon- ey, made by a few humans in charge, can have disastrous consequences that can wipe out entire countries.

You need to understand what I talk about in this book. This will help you avoid the scams. Get started in the right places. And understand that this trend is only the beginning. No matter how late you think you are in this game, we are still only in the first inning. But this evolutionary direction is only one aspect. This boils down to a five-second history of money.

A good answer: Money is the bubble that never pops. Why do we have money in the first place? For instance, through savings from the hard work at a job. Or you build a business that has value and you sell it. Or you sell a house. You created this value and it has to be bottled up somewhere. Like a genie in a bottle. So later you can unleash the value and make all of your dreams come true. Originally it was resources you simply had on your land.

The land itself. Later it was metals. Gold has some intrinsic value. It can be used as an electric conductor, for instance. It has antibiotic properties. The rest of the value is that for millennia, people have relied on it as a store of value. People buy necklaces or rings or other jewelry not only as ornaments but as convenient ways to travel with this store of value. And for a long time, gold was used to back paper currency.

And bitcoin is a store of value. Argentina is known for being a horrible country as far as how they treat their currency. And whenever it looks uglier than usual, bit- coin spikes. Because the wealthy have gotten smarter. So they use bitcoin. This is the canary in the coal mine. A clue as to what will come.

Argentina, in its wretchedness, has pointed toward the future. As our faith in humans disappears, our reliance on stable and trust- worthy data will rise. B To pay for things. And to sell things. First there was barter. But think about the problems of this. For every two items, people had to figure out what the items were worth relative to each other.

If I had a pair of shoes and wanted an apple, how many apples would I get for a pair of shoes? Do I need to cut my shoes in half? Money made out of hard-to-get metal became a common store of val- ue that can be easily traded because one side of the transaction always has the same value. So negotiation became much easier. What if supply went up and nobody told us? It answers why the rise of cryptocurrencies is just an inevitable and natural evolution of money.

From bar- ter to precious metals to government-controlled currencies to where we are now. We will see that even in the history of money, and not just the evolution of every industry, the demand for a data-based currency solves critical problems that must be addressed in the decades and generations ahead. Many things have to now happen. James tells his local bank. They tell the local reserve bank. And finally Joe goes to his ATM and takes out the money.

There was the possibility of human error at every step. There were also transaction costs at every step. These transaction costs are the built-in inflation of a centralized banking system. But sometimes it does. C Not only is human error a risk, but humans controlled the value they sent. Hidden transaction costs are baked into every step of the system. Value is determined by supply and demand. These issues have always existed and they have toppled empires, but so far the United States has proven superior to the fallen and forgotten.

Hopefully that will always be true. When and where and why and how is not known. All we know is direction. Direction is the philosophy of cryptocurrencies. Anyone who has a copy of it can do a full validation of the transactions in the full chain.

Historically, it was the central bank that validated the transactions. Now, blockchain allows everyone on the network to have a copy — and autonomously validates all of the transactions together. You can see how this eliminates not only the need for a central bank — but also the need for human intermediaries at all.

Security: If James sends money to Joe, Joe gets it. Decentralized: There are no geographic borders to the currency. Anonymity: Nobody needs to know about my transaction. Controlled supply: It should always be known by every party how much supply exists and under what conditions supply would stop and, in probably every case, whether supply has a maximum.

For instance, the maximum number of bitcoins that will ever be mined is 21 million bitcoins. This aspect exists only because of the rise of data. But I will talk about it in Crypto Corner. I will say this… Possible applications in the cryptocurrency space meaning the func- tionality is built into the data itself include data storage, the internet of things IoT , digital health care, escrows and wills and on and on. As I said in the last chapter, cryptocurrencies are just the natural evolution in money.

And there are plenty of reasons to look forward to their rise. Historically, cryptography was the art of keeping secrets from your en- emies using mathematics — or at least attempting to. Like the Enigma Machine. It was weak.

Our cryptography today is very strong. You can put data through it and the cryptographic function complex math formula transforms it into something incredibly unfamiliar from its original state. The transaction is now there in the block. The more time passes by, the more the amber accumu- lates and the harder and harder it gets to remove the fly from the amber. So a block can be likened to another thin layer of digital amber and the blockchain is the collective depth of the digital amber.

Something like that. A blockchain A guarantees the correctness of its past and present data and B guarantees the correctness of its future state and data Blockchains replace intermediaries with mathematics. Before block- chains, digital currencies had to run through central servers and be logged by central bookkeepers. Your money had to rely on several single points of failure before it would reach your intended destination.

Blockchain solved that problem. This is all greatly oversimplifying. Which is part of the privacy of the transaction and also ensures that no one source is controlling the validation and then possibly faking transactions or minting more money. But there are also downsides to these points. The good: A A standardized and neutral confirmation policy backed by soft- ware that has no human agendas.

What does this mean? Imagine I want to send Joe dollars to buy his house. This is OK, but at each step, someone could be untrustworthy. They are all humans, even the government humans subtly influence the price of the dollar and also share details of the transaction with unfriendly parties the IRS.

Also, each step in the above has a transaction cost. So inflation is built into the system. If this were a bitcoin transaction, enough miners need to approve that this transaction is valid. So even if a few miners are not trustworthy, the bulk of them will be, and we can trust that the transaction between Joe and me is legit. As well as have high security and avoid forgery. This reason is sometimes the basis for ICO rating. This was also originally the entire reason for the origin of money as opposed to a barter system which requires an exponential number of negotiations to determine the correct exchange rates between each object.

Crypto is just the next step after that. For bitcoin, the cost might be zero depending on your exchange , and miners get paid by getting more bitcoin depending on the computation power used to verify these transactions. One more good: Blockchains are incredibly resilient. A blockchain can survive unaffected as long as just one stays alive. With bitcoin, nodes are running all over the world.

The power is distributed. To kill it, you have to erad- icate it completely, globally, totally, without fail, all at once. This is very hard to do. The bad: Miners approve transactions one block at a time. A block is a set of transactions.

Blockchains are slow. Blockchains are slow because blockchains are extremely inefficient — especially compared to Visa, MasterCard or PayPal. Decentralization and censorship-resistance. Blockchains are inefficient. That software layer involves humans humans are bad , which invites good players and bad players to be involved hence, the Mt.

Blockchains are very hard to scale. In exchange for security, trust, fewer middlemen and avoidance of gov- ernments and boundaries, society pays in computational costs, storage the same blockchain stored on millions of computers is a waste and slower transaction speeds. And the software layer above the blockchain needs to evolve, which it is the same way internet software evolved post This is the ENTIRE reason multiple currencies exist and why there is a huge need to keep things simple and not get caught up in the hype.

Coins can be divided into two types: A They keep the same rough philosophy of bitcoin security, limit on minting of new coins, elimination of middlemen and boundaries, validations of trades, impossible to forge. Unfortunately, the only way to know this is to read the code, and there are hundreds of thousands of people using these currencies right now, unaware of the trap they are in. So… why more than one?

Or you can just copy and paste from other currencies and add features you like. Sure, most of them will be useless. I think there will be many winners. Data-based currency is an important evolution. And the children inherit traits from the parents. There are many valid currencies. Because dollars are in America and euros work in Europe.

This is based on the arbitrary and fictional geographic borders that were set up through human-led trade agreements, wars, etc. With cryptocurrencies, there are no geographic borders. Bitcoin and ether, for instance, work just as well in every single part of the world. For instance, upon writing this book, bitcoin is very slow to validate a transaction. I found a possi- ble solution. Another problem: privacy.

Bitcoin transactions have privacy. Legitimate problems in certain cases and a lack of geographic borders are what create new cryptocurrencies. B A data-based currency can have some functionality. Your data sits on servers owned by Google or Dropbox. There is a potential for human error and privacy loss. This is a lot for this introduction.

I will describe the size of the opportunity in a future issue. Because in any eupho- ria, criminals are created. We saw it with internet stocks in ; we saw it with hedge funds in the s; we saw it with mort- gage-backed securities in and now we are going to see it in cryptocurrencies within the next year or so. But the industry itself will boom.

This was a lot for one issue. And cryptocurrencies are a very compli- cated subject. Like I said, to actually know for sure if a cryptocurrency is legitimate or not, the only way is to read the actual software that created it. The good news is that, unlike the dollar, the software is available. Geographic boundaries create new currencies. But geographic boundaries are man- made and artificial, and many possible untrustworthy middlemen are required.

The ones I recommend you take a look at are: A. Coinbase — the most mainstream option. Certainly the most established. Buying and selling is easy and your bitcoins are insured. ICOfuffer — Another great choice. Kraken is known for its security, support and low fees. Signing up and getting started is simple. If you can use PayPal or online banking, you can figure these out fairly quickly. Cryptocurrencies are the first form of money you can store in your brain. Let me unpack what I mean by that.

Your private key unlocks your funds. The exchange does. One great thing about cryptocurrencies is you can become your own banker — so keeping your crypto on an exchange defeats this purpose. They have one vector of attack and, if hit hard enough, they come crashing down.

So how do you secure your coins private keys? Store them in your safe, hidden compartment or in a fake can of hairspray buried in your backyard [somewhat difficult, highly secure] D. Well, sorry to send you off, but the easiest method, as usual, is to Google it. The security of your coins is as strong as the security of your device.

If you want maximum security, I suggest you either: A. Secure your money in your brain B. Secure your money in your safe C. Most recommended Secure it in a cold-storage wallet device although this choice is limited to a few coins. Remember: The reason crypto exists is so you can better control your own money. How to create a brain or paper wallet Cryptocurrencies are the first form of money you can store in your brain. There are many ways to do this.

This process can get extremely compli- cated. First step: Go to WarpWallet. You should be shown the same page. And put an email in the email box. I want to reiterate the importance of a strong passphrase. Meaning, given enough time, hackers could figure it out by testing out every possible combination of characters.

Strong passwords are meant to make this process as cost-prohibitive and time-intensive as possible. The purpose of a brain wallet is not having a paper trail. Write it in your journal, coded within every sev- enth word. Write it in a book by circling the letters on every third page. Get creative. Or just write it down and keep it in a VERY safe place. If you go the paper wallet route, you have two choices: 1. Your QR code will make it easier to spend your funds in the future.

More on that in a moment. One inside your home. One outside your home. And another elsewhere. You decide. You know best. Important: The privacy risk in other people knowing your public key is they can look up how much money you have on that particular address. Something to keep in mind. Destroy all evidence before you log back in. Copy your public bitcoin address and go to your chosen exchange Coin- base, Kraken or whatever you choose.

Pro-tip: Always send a tiny bit on your first go to ANY address to test it out. If your computer is compro- mised, hackers can replace your address with theirs in your clipboard. Access and spend your bitcoins If you chose the brainwallet option, simply open up your Warp Wallet again preferably offline and enter your passphrase and email.

Grab your private key. If you chose your paper wallet, you already have your private key. Get it. Claiming the funds requires specific software. There are varying degrees of safety when doing this. The first is a way to put ALL of your funds on a web wallet. The second is a way to do a partial spend in which the wallet de- stroys your private key when the transaction is over, keeping the remaining funds secure.

An email address is optional but helpful for re- covering your account should the need arise. Pro tip: Use a password manager like LastPass to create a character password with uppercase and lowercase letters, numbers and special characters. Click it. Save your Wallet ID in a safe place. Wallet ID and Password. Be sure to check your email and verify that. And then, if you wish, enable two-factor authentication using your mobile number.

Meaning, before you log in, you must verify a code sent to your phone.

Millennial investors are looking beyond traditional assets such as stocks, bonds, and real estate to find opportunities to make their fortune.

Many young people are launching their own startups, investing in startups, and joining the gig economy among other things. Interestingly, cryptocurrencies such as Bitcoin, Litecoin and Ripple are gradually rising in prominence as an interesting way to make your fortune. Cryptocurrencies fundamentally refers to virtual currencies that are cryptographically encrypted to prevent their duplication while the records of their transfer of value is stored on a blockchain.

For a beginner trader or investor, it might be somewhat hard to make heads and tail of the similarities and differences if any between coins, tokens, and altcoins. The industry is not making much effort to differentiate between the different types of cryptocurrencies. For instance, you can store coins, tokens, and altcoin together in multi-cryptocurrency wallets and many new cryptocurrency traders erroneously think that coins, tokens and altcoin all mean the same thing.

This piece provides concise information that could help you identify and differentiate the different classes of cryptocurrencies. A cryptocurrency coin is primarily designed to facilitate the transactional transfer of value. Bitcoin and Monero are two examples of cryptocurrency coins in the market. Did you know that those currently or planning to provide services surrounding cryptocurrency may need a money transmitter license based on state or federal rules?

These coins are regulated and are the real deal. Cryptocurrency coins can be further categorized into groups based on their use cases. For instance:. Value coins such as Bitcoin and DigixDAO are transitioning from being used for transactional purposes to become a blockchain-backed store of wealth.

Bitcoin is the oldest cryptocurrency in the market and its blockchain has never been hacked in the last 9 years of its existence. Stable coils such as the Tether could also qualify as value coins because their value is pegged against a fiat currency. Transactional coins tend to have near-instant settlement and practically negligible network fees. Privacy coins such as Monero are created to offer users with the original promise of privacy and anonymity that cryptocurrencies could offer over fiat currencies.

People who want a layer of anonymity on how their cryptocurrency holdings would love Monero for its stealth addresses and ring signatures. Cryptocurrency tokens are primarily built to serve utility or security purposed on a platform built on a blockchain such as Ethereum or Stellar. While Ethereum itself is a platform for building and hosting decentralized applications, the cryptocurrencies used on such applications are usually referred to as tokens.

All cryptocurrencies used on ERC platforms are tokens. Utility tokens are designed to provide access or for transactions within a network or platform. Tokens such as Binance Coin and VeChain are used to access network features such as discounts on Binance Exchange and to track orders on VeChain respectively. People who hold security tokens can vote, weigh on decisions, and expect dividends on their part ownership of a blockchain venture.

Other types of tokens include network tokens which are designed to incentivize people to the growth and development of a blockchain. A hybrid token could be a mix of utility, network, security token. An altcoin is fundamentally a cryptocurrency that started with the same source code that was used to create Bitcoin—but with certain code modifications that makes it different from Bitcoin.

Altcoins include Dash, Bitcoin Cash and other future forks of Bitcoin. Even digital money requires a wallet. You store your cryptocurrencies in a wallet. Also, you can purchase cryptocurrency, buy into an initial coin offering ICO , or execute smart-contracts using the wallet. Every wallet has a public address and a private address. The public address is the address where you receive funds from people.

Never share your password. Otherwise, you might lose all the money in your wallet. Blockchain , regarding cryptocurrency, deals with the way in which data is structured. Also, it records all transactions to keep track of who had paid what and how much. Moreover, it makes payments faster and more secure. This process altogether throws light on Cryptocurrency Mining, which is an interesting concept again.

Crypto miners verify the transactions recorded in the blockchain and write them into a general public ledger. Initially, the seller and buyer need to sign an agreement. The transactions are to be held only after checking whether the requirements are met or not. Recent years have seen an immense increase in awareness about cryptocurrencies, which are based on the invention namely blockchain technology. And with the increased awareness, it can easily be said that more and more people are now investing in bitcoins and cryptocurrency in order to make some profit and have assets for themselves.

While cryptocurrency can be bought through online exchange sites , there are various cryptocurrency wallets which people can use to keep their cryptocurrency safe. Bitcoin hardware wallets are considered more secure than other wallets. These cryptocurrency wallets come in two categories, either as a connected device, which performs various tasks of any other wallet by helping you select which deals you wish to trade in, or the other option is a disconnected device.

Other than these hardware mining bitcoin, other cryptocurrencies such as LiteCoin, Dash, Ethereum etc. Ledger Nano S : One of the more affordable hardware wallets, available in the market which enables storing multi-currencies, is made as a smart card device. It has free updates, and its user interface is compatible with all software, making it a hassle-free device.

Trezor : It is another form of a cryptocurrency wallet that can be used to store bitcoins and make easy transactions. The user can validate transactions through the device, merely by clicking the correct buttons. It is designed in a manner that the user will have to facilitate each and every transaction, as all the requests would go through authorization. Additional feature of KeepKey is that is can easily be integrated with any other wallet software, by generating private keys and storing them.

Every day, new people are discovering the benefits of bitcoin and cryptocurrency. Many have purchased their very first digital asset from exchanges such as Circle Invest or Coinbase. However, only a few will have learned how to keep their private keys secure so that they can really call themselves the owner of those precious coins. This is a fact that will become an increasingly important one to know as bitcoin grows in popularity. The digital currency is being used more and more widely in a number of industries.

A private key is a secret alphanumeric code mathematically paired with your public key- the alphanumeric address where you receive payments. Private keys enable you to spend your digital currency and ensure that ownership remains under you, as long as you keep the alphanumeric code a secret.

An example phrase would be 12 random words that the software client gave you, which you need to back up, noting it down in the exact order that it was given to you. You can use the phrase to recover your cryptocurrency, using either the same wallet or a different one. The files should be imported into a compatible wallet to provide access to the coins associated with the keys.

The files should be safely secured. You can hide and encrypt them in folders to prevent access from intruders. These are two ways of securing ownership of keys, which both occur during the cryptocurrency-import process. So the coins remain linked to the private key that may be linked to a paper wallet, for example. Each wallet can now access the funds tethered to the private key until those funds have been spent.

Sweeping is essentially importing, but the private keys go to a different address entirely, and the original imported key set is emptied and rendered invalid. To summarize, keys can be stored in Mnemonic phrases, JSON files, and via importing or sweeping, and every cryptocurrency owner must know how to access them.

After all, the main benefit of owning bitcoin is that you can essentially act as your own bank. What is the future of Bitcoin? This trend has been continued over the course of the last 18 months, with a sustained decline in value during prompting some to suggest that the Bitcoin bubble was finally about to burst.

But is this really the case, or is the cryptocurrency simply declining in line with its uniquely volatile nature? In , Bitcoin enjoyed a truly historic and unprecedented price run in the markets and one that looked to have catapulted the leading cryptocurrency into the conscience of mainstream investors.

What goes up must come down, however, and this adage could have been invented with Bitcoin in mind. The market of cryptocurrencies is similar to the stock market, fast and unpredictable. Nearly every day new cryptocurrencies appear, old ones die, early adopters get wealthy and investors lose money.

Every cryptocurrency comes with a promise, mostly a big story to turn the world around. As per the research carried out by Technavio analysts, in , the worldwide cryptocurrency market grew remarkably by Websites like Overstock. Note that other altcoins like Litecoin or Ether are not accepted. However, the fact that Bitcoin is accepted is a step forward towards the adoption of other cryptocurrencies. A currency without a government, something necessary. This option is best for users who want to make money consistently and let their money make them money.

A good number of experts are saying Bitcoin will reach over 10k by the end of December. Do you have any suggestions or how to go about this? Thanks for sharing, Brian. Would you recommend Litecoin? A small investment of course. Then I heard good things about Binance and Bittrex. I would stay away from Kraken. If some one desires to be updated with hottest technologies then he must be visit this website and be up to date every day. It contains pleasant stuff. I was extremely pleased to discover this post on crypto.

I want to thank you for your time due to this wonderful read!!
