I recently realized a human-style position management rule: don't let any single trade determine your mood today.

If you can't hold onto spot, it's mostly because you didn't think through the worst-case scenario and how long you could endure it when you bought;
For futures, frequent liquidations basically mean you're treating "possible volatility" as "won't happen." When leverage is high, a small market shake can wipe you out.

Now I treat it like a household budget, first considering fees and slippage as fixed expenses.
Before opening a position, I ask myself: if I lose so much that I can't sleep, then my position is too big.
Recently, the main chain has been congested again before and after the upgrade.
People guess whether the ecosystem will migrate. I’ve become more laid-back—during on-chain congestion, I do less fiddling, preferring to miss out on a bit rather than let costs and emotions take over.
That’s how I’ll proceed for now.
