There is no single best cryptocurrency, but there are best cryptocurrencies for certain use cases. For example, Bitcoin is the best cryptocurrency to use as a reserve asset because it has the most widespread adoption and a finite supply. Most of the best cryptocurrency projects are in the top 50 market capitalization of cryptocurrency. Most small market cap cryptocurrencies have questionable use cases or have underdelivered on their promises. Small market cap cryptos are generally riskier than larger market cap coins like Bitcoin and Ethereum. It’s important to invest in cryptocurrencies that have a solid team backing the project. To get information about a cryptocurrency, it’s best to read the cryptocurrency’s whitepaper. This will give you an idea of how the crypto works and what its intended use is. Decentralized finance (DeFi) cryptocurrencies are some of the hottest altcoins of 2021. Altcoins are a general term for any cryptocurrency other than Bitcoin. DeFi tokens are typically built on Ethereum’s blockchain and replace traditional banking functions with code. Popular DeFi tokens like yearn.finance, Compound and Uniswap are up over 500% in the past 6 months.
