I have a major issue with Cryptopia that I hope isn't their fault. When I go to the settings page and try to change anything, it says I need a 4-8 character pin. I see no place to enter a pin. This gives me a red flag.
Hey mate I'm an admin at Cryptopia and did you ever set a pin for your account? Cause I know that people can set a pin number that needs to be entered for all sorts of things like whenever I log into my Cryptopia account I have to enter my 4 digit PIN after my login and password are entered. If you don't remember if you did or not just open a support ticket and I'll make sure that I bring it to the attention of the owners ASAP to help you get the problem fixed

Cheers
