True, but Bitcoin is the one that people actually speculate in. Ethereum seems to be in some kind of transition phase. Tether is not designed for speculation, and operates more on a Proof of Shenanigans principle. So it seems the highest capitalized Proof of Stakes cryptocurrency right now is Cardano, which is tiny compared to Bitcoin.
