Brothers, I want to say a harsh truth. You may have too much confidence in yourself, but as long as you touch contracts, there is a high probability of going to zero. The probability I am talking about is ninety-nine percent. There's also a ghost story: a 1.1 times leverage can also lead to liquidation, and the probability is not low. So staying away from contracts is the long-term path for you in the crypto world. Don't go all in; while going all in may not lead to zero, it can still leave you in an irretrievable situation!
