#BTC Don't worry if copy trading contracts are not done frequently, because I need to ensure over 95% win rate for this part. Of course, the return rate won't be low; even if I operate once a month, the return will exceed 50%. The key is to hold a Short Position 99% of the time, which is an anti-fall artifact. However, even with a 95% chance of rising, there is still a 5% chance of losing money. Either stop loss or the chance of getting liquidated is very low as I will control the position. Make sure the capital allocation is reasonable. Risk is borne by yourself!
