I think the best and the safest should be a priority. Binance is a good exchange and low on fee. Alsa Cobinhood doesn't get a fee (%0).
Binance can block your account, however, Bittrex does, too. I have had similar problems several times, so I believe that a safer way is to use exchangers without registering. Perhaps you need to pay attention to changenow.io. They have a fixed rate, claims are processed quickly and there is no registration. This is one of the options, now there are many exchangers, but this one I use at the moment.
It may not get you the best prices like does in the exchanges so when someone cares about the fee they will lot care about the price as well so using the exchange with hih price needs to be the priority.And using decentralized exchanges can make us to spend less fee or no fee but still they were not at their best like the centralized exchanges.
