CHAPTER 1
Welcome to the Cryptocurrency Craze
In a matter of only a few years, bitcoin has transformed from a theory into one of the eraâs most closely watched and intriguing investment trends. Potential for the coin and other cryptocurrencies now run the gamut, depending on whom you talk to. Some prognosticators have argued that the price of bitcoin will reach beyond $100,000. Many others claim itâs a bubble on the level of the largest market mirages in history. Such is the world of cryptocurrency investing where the truth likely lies somewhere in the middle. Now that youâre thinking of entering the space, make sure to embrace some of that excitement, but also keep in mind what youâre buying when you declare yourself a crypto investor. Itâs far more than purchasing a digital coin. This chapter offers an initial explanation of cryptocurrencies and will serve as a first step on your new journey.
What Are Cryptocurrencies?
At its basic level, cryptocurrencies are a very simple concept. Theyâre digital coins, created online, and meant for online spending. Developed via software code, cryptos are a way to transfer value, most often via digital means, like when youâre purchasing something online.
Take a very simple scenario, such as using a quarter to purchase a piece of gum. When you buy that gum, youâre giving the quarter to a shopkeeper in order to pay for the slice of gum. The quarter is a tangible coin that a US shopkeeper trusts. He knows that if he takes the quarter, it will cover the cost of the gum and the profit that he expected to gain from the sale. Itâs a very predictable transaction. A quarterâs value doesnât change all that dramatically in a short time. What will cost twenty-five cents today will likely run twenty-five cents tomorrow. (Over many years, that quarter wonât buy you as much, due to inflation, but for the short term, it does, which is valuable for commerce.)
One bitcoin is essentially the same as a quarter except itâs not tangible. Itâs a piece of code, and only you, as the owner, have the identifier, which is known as the coinâs key. You can pass that identifier on to someone else, in order to purchase an item. That person then receives a new identifier for the bitcoin, and the old identifier becomes obsolete. You canât actually hold bitcoin. You canât feel it. But when someone accepts bitcoin, she is viewing it the same way as that quarter.
But one bitcoin has grown to become much more expensive than one slice of gum. Thatâs because a whole community has grown around the cryptocurrency craze, willing to give bitcoin owners more and more for that one coin.
Why Would Anyone Want This Digital Coin?
If bitcoin and other cryptocurrencies function just like regular money, then why would anyone want to use them instead of the fiat currency (that is, the regular currency) that we all are used to? Itâs a fair question, one that the world has only begun to sort out. The answer depends greatly on who you are and why youâre choosing to use the coin.
The Anti-Federal Reserve Crowd
Early adopters saw bitcoin as a tool to spend without requiring a central bank to dictate the terms of the currency. Regular currency, like the US dollar, is subject to inflation. This is, to an extent, controlled by the Federal Reserve. It increases or decreases the amount of money flowing through the world markets through its use of interest rates. On a very basic level, when thereâs more money flowing into the market, then the supply rises, decreasing the value of one dollar. When the Fed restricts dollars, then the value rises. The Federal Reserve does this to retain a consistent inflation rate, so the economy doesnât grow too fast. Hyper-growth can lead to an overvaluation of goods you purchase, which would hurt the currency. Hyperinflation leads to a devaluation of the currency altogether and the Federal Reserve is mandated to try and hold inflation in check.
Digital coin enthusiasts donât believe that government entities should have the power to dictate these fluctuations in the money supply. One of the original goals of a cryptocurrency is to avoid inflation altogether. Thatâs why bitcoin has a maximum number of coinsâ21 millionâit can ever have in circulation.
The Business Case for Cryptocurrencies
What started as a libertarian dream, however, actually has a legitimate business use. It costs money to spend money. As odd as that is, thereâs a reason banks and financial institutions have grown so large. Itâs because they can collect fees in countless number of ways as money moves through their systems. For businesses, this can become very costly.
One of the easiest ways to imagine this is when youâre going on a trip to Europe and you have to exchange dollars for euros. When you go to the exchange counter at the airport, you not only receive less money back than you put inâbecause the dollar is worth less than a euroâbut you also lose a large chunk to a fee that the exchange agency charges to give you the euro. Now imagine that on a wide scale, where a business is making exchanges in the millions of dollars every day. Clearly there is an incentive to reduce that cost.
Thatâs where a digital coin has an advantage, since it isnât tangible. It can serve as an independent third party. Instead of going to a teller, you could use bitcoin to exchange the dollars by buying bitcoin with US dollars then selling them for euros once in Europe. The transaction is processed on bitcoinâs decentralized platform, leaving the transaction fee for processing the digital coin as the only fee the company has to pay. That saves you the cost of the much higher exchange fee created by the middleman. Financial institutions and other organizations are seeing the value of that, particularly in areas where the local currencies arenât as stable.
The Everyday Use of Cryptocurrencies
When evaluating why you and other regular spenders of currency would want to use cryptocurrencies, the discussion becomes a little more difficult. While there are benefits to a digital coin thatâs un-hackable, lives online, and will transfer almost immediately to the retailer when you purchase an item, it hasnât outweighed the ease of use and trust in the American dollar. Whether cryptos become a more prominent tool for everyday purchases depends on the ease of use. Regular consumers are going to spend the currency thatâs safest and simplest for them to use. Right now, thatâs the US dollar. If there was a reason for bitcoin or another cryptocurrency to replace the US dollar, and it was as easy to use as dollars are today, then it could grow. But that reality hasnât presented itself yet.
Itâs, however, still early days in cryptocurrency usage. To get a sense of just how early, letâs look at how the entire market began.
An Origin Story
Maybe you believe you already know how you feel about cryptocurrencies. Maybe youâre reading this to get an understanding of what exactly cryptocurrencies are before rushing to judgment. Either way, you should know where they come from in order to theorize about their future. Their origin story also provides a backdrop on why the technology supporting cryptocurrencies has the potential to shift the way the world operates.
Satoshi Nakamoto and the Creation of Bitcoin
Bitcoin, the original cryptocurrency, has an origin story that contains a number of mysteries, mostly because the creator of the coin has never come forward and proven that he or she published the concepts that would launch the crypto craze and form what you now know as bitcoin.
In 2008, an author using the pseudonym Satoshi Nakamoto published a paper outlining a new structure to develop a decentralized, peer-to-peer currency. In the paper, Nakamoto explains the concept of the blockchain, which produces a decentralized digital ledger and will become the backbone to bitcoin. Many enthusiasts had attempted to launch a digital currency in the early 2000s, but it wasnât until this framework publishedâin which the notion of the blockchain was describedâthat the ability to structure a currency completely decentralized from any oversight was shown to be possible. The author of the paper remains a mystery to this day.
Nakamotoâs vision worked because she or he conceptualized the notion of removing the requirement of trust in order to process a payment. For instance, when you pay by check, youâre trusting that the bank will provide the funds to the vendor based on whatâs in your checking account. The vendor accepts the check, trusting that the bank will ensure you have the funds for the service provided. The concept Nakamoto described removed the notion that vendors and consumers needed a third party, such as a bank, to provide this trust. Instead, this blockchain, or digital ledger, would verify the information as the transaction unfolds. Therefore, if you were trying to spend all your bitcoins on a car, the blockchain would first double check all the transactions ever provided by you to ensure you have the funds to supply the car dealer with the amount of bitcoins required for the purchase. Trust is no longer a factorâthe blockchain verifies that you have the funds. This opens up dramatic opportunities to bypass traditional financial systems.
To this day, despite many efforts to uncover the person or group behind the pseudonym, the identity of Nakamoto remains a mystery. Some have claimed that Craig Wright, an Australian entrepreneur, is Nakamoto. But efforts by Wright to prove this have fallen short.
Bitcoin Changes Everything
Shortly after this concept paper was published, Nakamoto created the first bitcoin. This technological breakthroughâthe blockchainâseparated bitcoin from all other previous attempts to develop online or digital currency. From this code and concept, many other cryptocurrencies have been birthed in an effort to fix problems within bitcoin, improve upon what Nakamoto started, or to jump into the cryptocurrency craze in search of a quick buck.
All Cryptos Have Their Own Origin Story
While you wonât find many cryptocurrenciesâ origins as unique as the patriarch coin, bitcoin, they all have their reasons for existence and a purpose for using them. The first piece of advice in investing in cryptocurrencies is to understand and recognize these origin stories. Itâs the first chance you have to see whether itâs a legitimate tool or a scam. Who is behind the cryptocurrency? Does it seem to be a viable concept? Does it make sense to link a cryptocurrency to this concept?
Reading these narratives will be a first step in recognizing whatâs worth investing in and which cryptocurrencies have value.
The Blockchain
Without a computer science degree, itâs not always easy to conceptualize the blockchain. Itâs essentially a digital ledger that tracks transactions within its code, providing a public, searchable, and infinite record of a cryptocurrency (or other item in which the chain was built to track). Whatâs different about the blockchain, separating it from past attempts to develop a digital currency? Itâs important to at least tangentially understand the mechanics of the blockchain in o...
