Spot positions can't be held, and contracts always want to leverage more. To put it simply, it's still a problem: don't let emotions dictate your positions.

For someone like me with small funds practicing order placement, the most practical advice is—first clearly write down the "worst-case scenario": if this trade goes against me, what's the maximum loss, and will it affect my ability to continue trading later.
If I can accept it, then go ahead; if not, then reduce the position to a tolerable level.

Recently, a bunch of narratives about AI Agents and automated trading have become popular again. It looks appealing, but I'm actually more concerned about the security details of on-chain interactions—permissions, authorizations, whether the contracts are reliable... Otherwise, no matter how fast the bots run, losses can come even faster.
Anyway, I now prefer a slightly messier curve rather than risking losing everything in one shot. Take it slow.
