I will suggest that for more easy and convenient way of running safe with the use of these centralized exchanges, we had better make use of the the common exchanges such as binance or bybit, this will be more safe for us because they are mostly used by many, am not saying kucoin is not fine as well, but there are some uncertainties in which we may count as abnormalities with the use of some exchanges, especially from the way of how they bill or charge their users.
