I recently discovered my typical problem: I want to run as soon as spot prices go up a little, and I want to add when contracts get excited, but the result is either not holding or getting liquidated... To put it simply, position management boils down to one thing: don't gamble with "money you can't sleep at night" on "something that will happen soon."

Now I forcibly divide my funds into three parts: one that I won't touch no matter what (the kind to pick up when it's cold), one for swing trading, and only the last part for contracts. If I lose it all, I just take it as a lesson learned—it's really just a few dozen dollars.
By the way, I watch Layer 2 daily, comparing TPS, fees, and subsidies. People talk tough, but I still focus on on-chain activity and real retention. When it heats up, I cool down; when it cools off, I wait patiently... Anyway, don't let emotions drive the boat.
