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.
https://www.bitget.cc/en/Is there any difference with margin trading or not? and it's really hard to use the exchange you've provided because I've never seen your exchange before and it looks like your exchange has just been established. I will not risk using this exchange until it is verified as safe for everyone
