You can’t really hold spot positions, and with contracts you can get liquidated if things go wrong. Put simply, a lot of the time it’s not that you misread the direction—it’s that your position is too “stubborn.” My own clumsy, plainspoken advice is just this: first, think through the worst case—if this trade is -30%, will I be able to sleep? If I can, then it’s too big; cut it down to the point where you can pretend nothing’s wrong, then enter again.

Contracts are even simpler: don’t treat “I can hold on for a bit” as a strategy. The moment you bring leverage into it, volatility turns into an emotion amplifier, and liquidation is often something you end up triggering yourself in a rush. I’d rather be a little smaller and slower, leaving “ammo” for a second chance.

Recently, that mainstream public chain is upgrading/maintaining, and in the group everyone is speculating whether the project will migrate. But I actually want to lower my position size a bit more… at this kind of timing, news moves faster than the K-line. Don’t let a few rumors push you right over the edge. Anyway, I’ll stay in the fog for now, and then when I come back, I’ll look at the data.
