List of Cryptocurrencies You Should Know – Built In

Most people can name at least one cryptocurrency, and chances are good it’s either Bitcoin or Ethereum. Since the debut of Bitcoin — and the dawn of cryptocurrency — in 2008 by the mysterious and pseudonymous Satoshi Nakamoto, tens of thousands of cryptocurrencies have been released. 
Estimates for the number of cryptocurrencies range from 12,000 to 19,000 worldwide. Some are more famous than others. Some have sprouted up only to wither and die under the heat of the rollercoaster cryptocurrency market: Total market capitalization reached $3 trillion in November of 2021 and in June of 2022, dipped below $1 trillion
A cryptocurrency is a digital currency — not tangible, as is a Euro note or dollar bill — secured by cryptography. Transactions of it are recorded in a digital ledger, which is a blockchain. Because it is secured by cryptography, this form of money is impossible to counterfeit. 
Cryptocurrency is also decentralized, meaning it can be bought, traded and used to purchase things without the aid of a third party, say a bank. Cryptocurrency issuers say that using crypto makes buying things, and transferring money, an easy, private and relatively low-cost proposition. Cryptocurrencies and the blockchains that support them are mostly open-source and supported by nonprofit foundations and global teams of volunteer developers who work for free.

Dive into the cryptocurrency world and you’ll see three words pop up when referring to crypto: stablecoins, altcoins and tokens. 
Stablecoins are pegged to the value of a hard currency, for instance the Japanese yen, U.S. dollar or Euro. Altcoins are anything other than Bitcoin, which is the original cryptocurrency. Tokens are synonymous with cryptocurrency and are used to describe any coin other than Bitcoin and Ethereum. 
This can be confusing because some blockchains, for instance Ethereum, issue coins that are both stable (pegged to a hard currency) and tokens (not stable). 
Avalanche (AVAX), a token on the Avalanche blockchain, was first released in 2020. It is traded on 25 exchanges. Interested parties can earn AVAX via participating in decentralized finance (DeFi) projects, including AAVE, which lets users earn interest and borrow assets; Benqi, an algorithmic liquidity market protocol; Curve, a stablecoin liquidity pool; and Sushi, a DeFi innovating platform, according to the Avalanche website
Binance (BNB) powers the BNB chain ecosystem, and is the native coin of the BNB Beacon and BNB Smart chains, according to the Binance website. BNB can be used to pay for trading fees on BNB’s decentralized exchange, pay transaction fees on the Smart and Beacon chains, and pay for purchase online and in stores using a Binance Card or Binance Pay, a contactless payment technology. Holders of BNB can also book travel arrangements on, according to the website, and donate on Binance Charity. 
Binance USD (BUSD) is a stablecoin, meaning it is pegged to a hard currency, in this case the U.S. dollar. Binance USD, a partnership between crypto trading platform Binance and fintech company Paxos, was launched in 2019, and is available to buy and trade on both companies’ websites, according to the press release announcing the launch. In July of 2022, Paxos announced it would begin releasing monthly reserve holding reports for BUSD and Pax Dollar (USDP), its own token, in the name of transparency.
