Maybe you can try the simulation trading first,I don't think it's that complicated.You can experience simulation contract trading without any cost.
I found there was a exchange has launched ETH / SUSDT, EOS / SUSDT, SBTC / USD and BTC / SUSDT simulation trading pairs.

I bet you didn't find that site, you made that.
Well, haven't check the site at the moment but in my opinion a trading simulation is good to understand how it works. But just don't take it serious, we often take profit easily in simulation but in real trading it is not that easy.
