I realize my biggest problem isn't not knowing how to read charts, but being too reckless with my positions: when spot prices go up, I want to buy more; when there's a two-point pullback, I panic and want to sell. Futures are even more outrageous—if I open a small position, I think it's too slow; if I open a big one, I just wait to be wiped out. To put it simply, position management in plain language: you first decide "how much am I willing to lose on this money," then decide how much to buy. Otherwise, relying solely on emotions to trade, no matter how much you practice, is pointless.

Right now, I keep it simple and rough: gradually increase my spot positions in parts, treat futures as insignificant little tickets, and prefer to miss out rather than leverage and gamble with my life. Recently, hardware wallets have been out of stock, and phishing links are everywhere—security is just as important. Don't wait until you're hacked or scammed to realize "I should have known better." Anyway, it's more realistic to first get used to not getting liquidated or clicking the wrong links than to dream of making a full profit in one shot.
