Trading pretty much comes with mistakes. More than likely, if you can manage to keep going, you'll make back what you lose as you learn. Of course, that's assuming you can learn. :P
Sometimes it feels like trading is just guessing and betting. It's not, no matter what anyone says. If there was any game at any casino that was as predictable as trading, casinos wouldn't run it, because it would bankrupt them. Instead they run only games where they have a distinct advantage.
I don't know if I can trade crypto anymore because I'm too emotionally attached to it as a buy and hold asset. If I were to trade, it'd have to be with new funds I deposited to treat as funny money or poker chips where there was no attachment. To do this, I might have to trick myself by trading coins I had no interest in, but had a strong understanding of from my years of tracking them.
Well, there are certainly tons of coins out there that might be alright bets, but you don't necessarily have to have any real attachment to. Even a few bucks is enough to start trading with. Hell, I've made quite a bit trading Dogecoin before.
