No more contract trading, both platforms have entered a cooling-off period. I didn't make any profits during last month's plunge, and I haven't made any profits during these days of surge either. Without discipline, it's hard to hold on. In the future, I will only go long using low leverage to borrow coins, taking profits at 1-2 points. After a pullback, I will continue to go long. Going long with 2-3 times leverage will be treated as spot trading without a stop loss. If there is a sharp decline, I will hold the position. It's also quite hard to get liquidated with 2-3 times leverage. I am no longer aiming to make big money. I will use this strategy to see if I can earn some pocket money.
