I set a pretty cowardly but effective rule for myself: if I can't hold the spot, don't pretend to be a long-term investor; if I really want to gamble, I can only use the money I can accept losing after a night's sleep. Contracts are simpler, don’t try to reason with the market, first reason with the liquidation price—getting too close is like booking your social death. Recently, with that mainstream public chain upgrading/maintaining, everyone in the group is guessing whether the ecosystem will move away. I think the first to move is often people's emotions: when nervous, they leverage more, add to their positions, and then explode in a chain reaction. To put it plainly, position management boils down to one human truth: don’t let one wave wipe out your mood and account for a week; only by surviving can you watch the show and have the right to laugh at others’ explosions.
