I often can't hold onto spot positions, as soon as it rises a little I want to "lock in the cat food first," but then I turn around and chase the high again; futures are even more ridiculous, holding on and holding on until a needle pops me... Later, I came up with a piece of common sense: don't take "wanting to make quick money" as ability. Divide your position into three parts, the long-term part really doesn't move (unless the project is ridiculously bad), the short-term part, if you lose, just treat it as buying a ticket, futures? At most, use them to pass the time, no matter how small the position, first think clearly about "how much can I lose in the worst case," don't gamble your living expenses on feelings. Recently, that mainstream public chain is about to upgrade, and the group is guessing whether the ecosystem will move away, I anyway first pull back, wait for the dust to settle before deciding, better to be cautious.
