I am no fan of Ethereum going POS, but what Paxful did is hypocrisy of the highest level. If they are really into POW and against the centralized nature of Ethereum then the fist things they would do would be
1. Delist centralized Tokens on Ethereum network (USDC and USDT)
2. Mark their platform decentralized like bisq and stop asking for KYC
They should do these two right away, if they hate centralization, they must not have a hint of centralization, they have to go all out and become a true believer in decentralization if they are really into " integrity Over Revenue " their so-called integrity will backfire and people will still believe that they are still profit-driven because of the profit these two stablecoins are bringing to their platform, you cannot serve two masters at the same time.
