If you do not have any experience with the future trading, maybe going into a competition is not something you should be doing. There are places where you can test how you could do trades like that in a demo situation. That way you won't spend any money on getting better and being in a competition. Of course they won't be as great as the real thing and you will not be doing all the same when you start to do the real thing.
However at least it is better to go to the real thing from the demo and knowing what you need to do, at least that way you wouldn't be zero about everything. After that check how you are doing and when you reach to a point where you are doing great enough to actually profit and also be good for a competition, you could join the real one.
Actually i would say the same thing on where, why would engage if you dont know on what you are doing? Its just a suicidal move and would definitely burn out your entire account balance.
Demo is good but its totally different when you are in the actual or real account situation where emotions would mixed up because it wont really be the same when you do trade
on a demo account.
Let me check where I can open a demo account and start practising. I don't think there will be one for Bitcoin Futures.
Dont have any experience on using up this platform but you can dyor;
