Binance is for me the best exchange that currently exists offering an excellent tax relationship, in addition to having its own BNB crypto currency that by owning it in our portfolio further reduce the taxes charged per transaction.
So far I have not had any problem within the platform, I have resolved the doubts at the time in excellent time, as well as the recovery of the 2 security factor I have managed to recover quickly having in my possession the backup recovery code offered by Binance at the time of registration.
