Futures are an excellent tool for hedging positions. I put the bot in short at the highs if a particular coin has shown strong growth in spot trading, and if you can guess where the high is, go for it.

$BTC people, please tell me if I am right or not, if I only work on futures in short with a minimal leverage of, say, x3
try to enter short only at highs, I think it is possible to earn well, since usually with such leverage it is unlikely to get liquidated, and discipline is the main thing!
