I only take one note: Don't treat spot trading as a belief to go all-in, and don't treat contracts as a gamble for a turnaround—first, reduce your position size to a level you can sleep peacefully with, take partial profits as it rises, and set stop-losses along the line when it falls. Don't keep an eye on the gossip about main public chain upgrades/maintenance and shake your hands to add positions, ultimately ending up unable to hold or getting liquidated directly. It's really unnecessary.
