A few days ago, I played a single bet with #交易故事 #BTC交易 . I closed it early, but since USDC has no transaction fees, this bet was essentially free. The contract transaction fees are quite expensive, typically about 0.02% of the position (margin × multiplier × 0.02%). Everyone should avoid frequent trading. If it's a market order, it's 0.05%. It's best to find a friend to invite you; make sure you can reach the person who invites you, or you can create another account for a 20% discount. The invitation code I filled in is one I found on YouTube initially. It's a bit stingy; they claim it's 25%, but if you don't meet the weekly standards, it won't apply. In the end, it’s better to have a stable 20% discount by yourself, so be very careful!!!
