Based on my experience in using the exchange market, I would like to suggest to you to trade on the exchange market:
1. Kucoin
2. Huobi Global
3. Hotbit
4. Gate.io
5. FTX
Those are top exchanges, surely recommended to use. But I'm surprised you didn't mention Binance? Do you have a problem with Binance?
By the way, IMO Hotbit isn't really friendly for withdrawal fees. Among those exchanges above, withdrawal fees in Hotbit seem the most expensive. Even if we compare with the withdrawal fees in Binance, Hotbit is still more expensive.
For example:Withdrawal fees in BinanceBTC 0.0005 (Network Bitcoin)
ETH 0.002 (Network ERC20)
Withdrawal fees in HotbitBTC 0.001 (Network Bitcoin)
ETH 0.012 (Network ERC20)
i am also have bad experience with hotbit ,beside withdrawl fee expensive , their GUI was not easy to operate. its just like gate it, i am confuse how to take market execution due too many column to filled. personally i am prefer using kucoin or ftx, they have good user interface and also friendly in withdrawl fee. trading volume as good enough to take limit or market execution.
