Honestly, it does make sense. I had already bought in at the 17k level for $wtf, with a target of 950k, and it actually got close. But looking back now, I still feel a bit regretful—missing out on the rally above 20k. If I hadn't been so eager to bottom out and exit at that time, I might have been able to enjoy bigger gains. Looking at the trading records now, the returns are actually quite average, not meeting expectations at all. Sometimes, this is the reality of trading: you can see the right direction, but not necessarily hit the right rhythm. Next time, I need to be more patient and not always think about quick arbitrage.
