Cool story bro, stable coin = shitcoin = centralized garbage . Don't buy them, don't support them, don't fill the bags of a few. Can't see a reason as to why not buying bitcoin and keeping it in your wallet?
Trading? That's just gambling with a nice mask, it's the same principle underneath, the poor gets poorer and the rich gets richer, imagine buying USD to trade it with EUR, who do you think profits from that? Think more.
