The bull run that began 2021 held up in January, with ETH consistently at ATH (At The High) prices last seen 3 years ago. Interest in crypto bumped up as retail investors saw the need for DeFi - r/wallstreetbets' bet against Gamestop shorts being rudely derailed by centralized players on Wall Street. Despite the hype, there is vast room for growth as many have not even heard of DeFi.

In this issue, we analyze the 2021 returns of 75+ top tokens in Ethereum with the help of a new data dashboard. Features added include sparkline charts of token holders for the traders and multi file source code search for the developers.

This time last year we first asked for your feedback on the Etherscan newsletter. Now is time to ask you again! Share your feedback and stand a chance to win $10 in ETH!
