FTX is also a new exchange, I have not tried to trade on it, but it is very similar to most, I see no reason to change it to Huobi. Yes, I only manage someone else's account on Huobi. I have my own accounts on Binance and Poloniex. Also, now there is a small account on Fybit. When withdrawing funds from Binance, they charged 2 times the withdrawal fee. I tried to figure it out through the support service, but they have a bad one, they did not help. I left an investment account with them, but the sediment remained, even if it was a small amount, but it was still stolen.
Yes, it is similar, especially if you try their mobile apps trading. I do not know if Binance charged 2 times the withdrawal fee because I did not check it. After all, when I want to withdraw, the funds will be bigger than the fee, so I think that will not be a problem.
You can leave your investment account there while searching for the other exchanges. I have already suggested it to you, and I hope you can get what suits you. Oh, how about Bittrex? Do you try it?
One trader I know tried to trade on Bittrex, but as I understand it, he mainly uses Binance, like most of my friends traders. Everyone who has large accounts uses Binance, but for active trading, including scalping, many are looking for a platform without KYC. Now there are not many such platforms, by the way, this is one of the reasons why I opened an account on Fybit.
