Cryptopia is one of the very few platforms that was developed without bad intentions hidden under the hood. At least easy to spot ones such as the options to disable email confirmations required for withdrawal paired with the inability to change your email address.

Many exchanges will not allow you to change your email address, which can be a big issue if you no longer have access to said email account.

So if an exchange requires email confirmation, you can't access email and can't change it, your screwed unless support helps.

With cryptopia the option can be disabled though you certainly will want to enable 2fa.

Always make certain to backup your master 2fa keys in a safe manner, such as PGP.
