These days, hot topics are rotating like fans, and as soon as attention shifts, I get itchy hands. The result is that I most easily pay tuition fees on slippage. To put it simply, while others are telling stories, you're eager to rush in, and those few seconds in the mempool are the favorite time for the snipers: you hesitate to change parameters, don't want to miss out, and when slippage is amplified, it's basically like shouting "Come and snatch me."

I now treat it as doing a "backup" — holding the main position as cold backup, hot topics as hot backup, ready to disconnect at any moment. When I see news about tightening or loosening compliance, or tax increases, emotions can push deposit and withdrawal expectations to extremes, so I need to be a step slower: first check if the trading volume suddenly thins out, if Gas has abnormal order stacking, if not, just set limit orders or split orders, or simply stop chasing… Anyway, getting cut once is much more painful than missing out once.
