Brothers, the contract is here again. This small B3 is only available for contract but not spot. I think it will rise when it rises, and it will fall at night or continue to rise until tomorrow. My trading strategy is to open long positions, and stop loss must be set at -20% of the opening price. If the direction is not right, open short positions immediately after stop loss to grab back the lost, but stop loss must also be set when opening short positions. Prevent long and short double kills. $BTC
