In your platform says you dont required identity verification to do a trade right? If that so, how can we determine the users if our account is safe and it wont be hack? There are times and not always thsat someone in the world will get hack or scam right? For me identity verification is really important so that you can guarentee that the person is using his/her real account.
Using 2fa you can confirm that you are the only person in control of your account without giving personal information.
2FA is very important confirmation because in this case only the owner can access the account. Maybe this platform has this kind of authentication because this is an effective way of avoiding the account to be hacked.
