Next to only Bitcoin, Ethereum (ETH) is the second most popular cryptocurrency in terms of market cap. It holds one of $470 billion, as of 10/27/2021, which is significantly larger than that of many Fortune 500 companies, including Netflix or Walt Disney Co. Vitalik Buterin created ETH in July of 2015, and since then the coin has seen significant growth, with an active community and team of developers who continue to find and fix problems within the ETH blockchain.
