Well that's part of the experience to be lost in futures I was in the same situation months ago. All my spot coins/tokens are converted to USDT just to try my luck on futures and try some of the strategies that I learned, but the result is pretty bad I lost them all. I am using higher leverage, like 10x to 20x with risk management, like using stop-loss, but in the end I lost them not instantly but gradually.
That's why right now I still keep trying myself to improve my strategy and learn more strategy, but this time not with high leverage. I play with paper money on TradingView and test out some strategies on futures with a small amount.
