I've always been like this: when spot prices rise, I get itchy and want to chase, but when there's a pullback, I can't hold on; then I switch to trading contracts to "improve efficiency," which basically means amplifying volatility, and in the end, a huge drop teaches me a lesson. Later, I came up with a simple version of position management: first write down how much I can lose, then decide how much to buy, don't do it the other way around. If you don't understand, just don't act—it's really a lifesaver—last time with that social mining thing, everyone was shouting to pay attention because they were mining, I looked for a long time and still didn't understand how the money was flowing, so I simply didn't touch it, and the next day, everything was a mess. Now I just focus on liquidity and funding rates; while it's lively, don't let your positions follow your emotions.
