Coinbase recently announced their intention to go public at a valuation of $100B. With Bitcoin trading above $60K, there is increased interest in the Crypto currency and Crypto-related stocks. The most promising that are currently listed are RIOT and MARA. Riot Blockchain and Marathon Digital Holdings are Bitcoin miners. Also GBTC is an OTC stock that holds Bitcoin in trust. Coinbase seems like the thousand pound gorilla to these smaller outfits.
