Imo, DEX is the future. Whether BTC is the adopted currency remains to be seen (unlikely.) My hesitation with BTC is the fact that 60% of its transactions are made through Tether, which is made out of thin air (like the dollar, but I digress.) Tether will crash soon, and BTC/crypto too. Something else will rise from the ashes.
Also remember, not your keys, not your coins.
