Hi. I'm new and I've been burned by trying to find an exchange/wallet where I can fund an account, buy coin for trading and holding (so earning higher interest is desireable) and then convert to fiat and withdraw as needed. I am currently using FTX-US to deposit USD and buy coin (problem: not all coins I want are supported) because fees are low. I will then (when deposit clears) send coin to Celsius wallet to store and earn interest until traded again. But I will again need to go back to an exchange in order to convert to fiat and withdraw. At least this is the perceived process I've learned so far. I have yet to complete this process. As you can guess, fees at various exchanges/methods have taken their toll. Any advice will be appreciated.
