Spot can't hold, and contracts always love to explode when held too long. Honestly, it's not about market conditions; it's about you making yourself "must." Here's a straightforward rule for myself: don't take on positions big enough to affect your sleep. Treat spot as storing old items—decide in advance when to sell and accept the drop; contracts are even simpler, just use small positions to test your emotions, if wrong, close it, don't hold on stubbornly until it becomes a belief.

Recently, before and after that mainstream public chain's upgrade/maintenance, the group has been guessing whether the ecosystem should migrate. I also glance at it, but I don't chase after news; unexpected volatility is the easiest way to break discipline. I no longer believe "this time is different, so exceptions are allowed"; once you break once, there will be a second time. That's it for now, log off when the time comes.
