Where is the safest way to create a bitcoin wallet?
In a trading site. It's safe because they have anothwr layer of security which are more likely 2fa authenticator or sms message which is impossible to break if you're very careful with your actions.
I didn't know that they are using it. I though it's just for email security.
A lot of
exchanges are using that. That's why cryptocurrency trading is safer that other platforms which uses fiat money. Aside from the security, cryptocurrency trading gives more freedom on your trading like arbitration, and etc.without charging you with taxes.
