Cryptocurrency All-in-One For Dummies. Peter KentЧитать онлайн книгу.
Heck, some people even think that Bitcoin may be the worst cryptocurrency to own or to invest in. This is because so many other digital coins are available that have made massive improvements to the Bitcoin model to avoid its disadvantages.
This chapter covers some of the most famous cryptos as of 2021. But because the cryptocurrency market is ever-changing, you also find out how to navigate your way through all the up-and-coming cryptos for years to come.
Celebrating Celebrity Cryptocurrencies by Market Cap
One of the fastest ways to navigate through popular cryptocurrencies is to check out their ranking based on their market capitalization, or market cap. Traditionally, market cap is the value of a company that’s traded on the stock market. You can calculate it by multiplying the total number of shares by the present share price.
In the cryptoworld, market capitalization shows the value of all units of a specific cryptocurrency that are for sale right now. To calculate a cryptocurrency’s market cap, simply multiply the cryptocurrency’s current price by its circulating supply. Circulating supply is the best approximate number of coins that are circulating in the market and in the general public’s hands.
Market cap = Price × Circulating supply

With a knowledge of what role a coin’s market cap plays in the industry, you can start to evaluate cryptocurrencies based on that metric.
MINEABLE VERSUS NONMINEABLE CRYPTOCURRENCIES
Where does cryptocurrency come from? Cryptocurrency can be mined — the least common form, actually — or it can be pre-mined.
To say that a cryptocurrency has been pre-mined, or is nonmineable, simply means that the cryptocurrency already exists. The blockchain is a ledger containing information about transactions. When the blockchain was first created, the ledger already contained a record of all the cryptocurrency that the founders planned for. No more will be added; it’s all there in the blockchain already.
Bitcoin
Ranking number one on the list, Bitcoin was developed in 2008. As of September 2021, Bitcoin’s market cap is around $951 billion.
A bit of Bitcoin background
But Satoshi’s anonymity isn’t really a big deal, because Bitcoin (and other cryptocurrencies, for that matter) is supposed to be open source and decentralized, as we explain in Chapter 2 of this minibook. In fact, according to Bitcoin.org, no single person or entity “owns the Bitcoin network much like no one owns the technology behind email.” Bitcoin users around the world control Bitcoin, with the developer improving the software and the forkers making some radical changes. However, the main idea behind Bitcoin and Bitcoin’s protocol can’t be changed.
In mid-April 2011, Bitcoin’s market cap was about $6 million. In April 2021, the market cap was over a trillion dollars. If you had bought 1 Bitcoin for $2 in November 2011 (something Kiana’s investor friends told her to do that she ignored), your single Bitcoin would have been worth $64,000 in April 2021. Of course, many initial investors bought more than one Bitcoin at the time, which is exactly how all those Bitcoin millionaires were made. If you had bought 100 Bitcoins in November 2011 for a paltry sum of $200, by April 2021 they would have been worth $12.8 billion!
But by the time everyone started talking about Bitcoin, it went crashing down to around $120 billion and stayed there for most of 2018. It maintained its number one ranking among all other cryptocurrencies, though. The main reason behind this position may have been that most people had heard a lot (relatively speaking) about Bitcoin but not so much about other cryptocurrencies. So even though they had several hundred other altcoins to choose from, even some that may have been better long-term alternatives to Bitcoin, most newbies who wanted to get involved in the market started out with Bitcoin.
Another reason for Bitcoin’s huge market cap is its accessibility. It’s pretty safe to say that all cryptocurrency exchanges (see Book 5, Chapter 3) carry Bitcoin. But not all exchanges list all altcoins, at least for now.
