Cognition! Regarding rebates, you don't have to ask me to open them, but you must know! Every contract transaction incurs a 0.05% fee. If you leverage 100x, that's 5% for opening and closing = 10% of the principal. If you spend $10,000 in fees in a month, the rebate rate varies depending on the exchange. Some give back $2,000, some $4,000, some $6,000. Without rebates, it's like going into battle with a wooden stick while others have a bronze sword. I ask you, how do you plan to play? Still not convinced?#合约 #加密货币 #btc
