Is it bitcoin or altcoin, if it is altcoin, can you specify?
I have traded both BTC/USDT and also altcoin/USDT pairs on futures and from my experience it is safer to stick with BTC/USDT futures trading. Although not as profitable as some alt pairs in the short run but with a good trading strategy and patience, it is much more profitable to use BTC/USDT pairs for trading futures. One of the worst Altcoins to use for futures trading are the meme coins. Now I stick with BTC.
I can't stand the risk of getting liquidated very quickly while trading future that was why I totally avoid trading future, however the best pair for high leverage trading is BTC/USDT being the most highly volatile pair while majority of other altcoins are driven by the movement of the price of bitcoin.
I am presently satisfied with trading with Isolated margin due to it lower risk though small profit is usually earned, I am very contended with it, bearing in mind that trading is requires skills, the more the skill the better for future traders.
