Many times the direction of the altcoins is correct, for example, going short 5 times, I set a stop loss, and then it first pumps a bit, just enough to liquidate me, and then immediately crashes. If I don't set a stop loss, it can first liquidate me and then plunge all the way down. It's better to stick to spot trading.

It's been three years, and I haven't made a single cent, yet I have to keep putting money in. Not once have I opened a correct position; when I buy dips, it rises, and when I buy rises, it falls. You say to buy both long and short, but this thing always moves in the direction that makes you lose money. I really admire those who make you cut losses; they are particularly shameless. Seriously, when you buy rises, it falls, and when you buy dips, it rises. What kind of loss is that? If you dare to cut losses, you will forever be on the road to cutting losses. The only way is to wait for the retail investors to take over your position. You buy the dip, it rises, and then you have to wait for someone to buy the rise, and naturally, it will fall back down. It's best to hold positions, to avoid frequently opening positions, wasting time and energy. The worst that can happen is a liquidation; it's really no big deal.
