I have used both of the platforms, crypto futures and pxtrader, and thinl:
IF you are an overall fan of futures, then it’s ok for you, but make sure you style of trading is intraday. The explanation is pretty simple, there’s funding fee for futures, because you trade with leverage, and it looks like swap fee. but the difference is that its paid every 8 hours, so if you hold if fora whole day, yougonna pay that for 3 times. THis si why it’s best to get it done intraday, and to get the lower costs is to be inside that 8 hour mark and put pending orders, and if you see that after like so many hours the trade is not going your way, you can close the trade before going away from the chart, just leaving it open is not a good idea.
If you want to trade crypto but for longer time, then you can try pxtrader becasue they have crypto with normal swaps, and there’s no comission, only spreads. IT also has some other assets too for those who enjoy like forex and I am surprised to see how many different currencies they have, like fxminors and exotics.
