I can’t hold spot positions—once it goes up a little, I just want to run.

Futures are even worse; if you keep holding them, you end up getting liquidated...
Later, I finally figured out the plain truth: don’t get carried away with your position all at once.
If you want to buy, do it in several rounds. If you want to open a futures position, think of it like buying a lottery ticket.
Take at most a tiny fraction of your total assets to play with—if you lose, it shouldn’t affect your sleep.
Don’t be stubborn about stop-losses. When the time comes, admit it and exit, otherwise even the trading fees can grind you down until there’s nothing left.
Recently, there’s been a whole bunch of stories about AI agents doing automatic trading and automatic on-chain interactions. It looks pretty lively, so I’ll just screenshot and save for now...
If I really end up using it, I still need to scrutinize safety first—check permissions, authorizations, and the contract address clearly. Otherwise, “automatic” just means it automatically sends your assets away.
In short, living longer matters more than winning one round.
