What exactly does the PIN on evo do? I have never had to withdraw BTC so I completely forgot my PIN, and have made several purchases on EVO. I dont want to lose my account with my history, but I am nervous to transfer BTC into the account now knowing that I do not know my PIN. Will I ever need to use my PIN to make a purchase? Can I reset my PIN? I do not know the mnemonic it prompts you to type in when trying to recover it.
No. PINs are for withdraws only.
Only with your mnemonic, which you say you didn't save. It straight up tells you that it's the only way to reset it. Why do you think it's the first thing you see when you make an account?
Since you're implying you haven't made an order yet the best thing to do would be to make a new account and save the mnemonic this time.
