Last night before bed, I saw someone watching large on-chain transfers and exchange hot and cold wallet movements, saying "smart money is moving"... The more I watch, the more I get scared. To put it simply, position management boils down to one thing: don't bet with money that affects your sleep. If you can't hold spot positions, it's mostly because your positions are too heavy, and a wave of retracement makes you nervous; futures are prone to liquidation, usually because you treat "possible mistakes" as "impossible to make." I'm now following the simplest approach: first treat a sum of money as tuition, then divide the rest into several parts to slowly enter, and if I make a mistake, I can still survive and wait for the next time. Anyway, staying alive is the most important.
