I just try maximum 20x leverage on OKEx perpetual swap, because the market is so violate now and if use 50x or more like you, you will be liquidated position easily. And for who said that margin is gamble, i think not. For gameble, you have 50% change but you will lost all if you lose. For margin you can control the risk by stop loss, and increase profit with greater leverage.
Yes, it is easily to be liquidated. But I accept risks and you know, I was liquidated several times, it is not something new for me. I know what I am doing and what are the consequences.
By the way Okex is about to launch 100x USDT futures and this product worth seeing. More gain on shorts, because you gain profit in usdt and not in falling asset
