I don't know much about what is "hot" in crypto exchanges, but FTX is saturating sports commercials and getting high-profile endorsers like Steph Curry and Tom Brady and sponsoring the Miami Heat arena. Crypto.com has the naming rights for the area that hosts the LA Lakers, LA Clippers, LA Kings, and LA Sparks as well as sponsorships of the Philly 76ers, Montreal Canadiens, UFC, and the 2022 FIFA World Cup.
Even if you believe strongly in crypto, Coinbase seems to be losing mindshare to competitors who are spending big. While some marketing spending might be considered foolish by some (I already know that Gillette exists and generally know what razors are available), with crypto they're probably targeting a lot of customer acquisition in a very new market. If FTX and Crypto.com become the faces of crypto to every sports fan looking to buy crypto, that seems like it would be a problem for Coinbase.
Coinbase might be better or worse than those other two, but as someone who has been watching sports I can tell you that FTX and Crypto.com are very front-and-center. If crypto is looking to attract lots of new buyers, it seems like FTX and Crypto.com are doing the marketing to make them first in people's heads.
