You will pay fees for your futures so you would end up slowly losing your capital.
I will use 1x, the fee will be very low. Not only that, the amount to trade with future will be slightly lower than what is in spot account that will be taken to future account, but the difference should not be that significant. I do not receive enough response from this thread, I will try it myself and see how it works.
yhup you should make research because not all traders here are using futures i guess, because of liquidation and the risk of course. Infact there's already some existing content especially in youtube about futures. maybe you can get more information through that way than here.
