What would be your suggestions to any crypto exchange to enhance security and avoid being hacked?
You should know that the exchanges have a big chance to be a target for the hacker and you should secure your account by activating the security that the exchanges suggest. You don't have to use all of your money to be used on the exchange because you know the risk. But I am sure that the exchanges will give high security to their member so their member can trade without worry. And the important is you should only use the exchange that is recommended by many people. Don't use suspicious exchange because the risk will bigger than the other exchanges.
