Iam not use exchanges for tradings. Because iam holding my valuble coins for longterms using nano ledger hardware wallet. Exchange using only converting for my coins. If you want to use exchange for short-term trading. I can use 2FA for high security purpose. Ex: google Athonicator and etc.
Will the google authenticator will matter if the main exchange has been hack?
I always have them on my security features which really add more guard on our account.
But what if the platform the one has been hacked? like CRYPTOPIA!
