The PIN is the four digits you entered during account registration it is not possible you have skipped that step since it is mandatory.
If this PIN is lost or forgotten, is there any way to recover it ?
Also what is your plan for any campaigns for your site on this platform ?
pin is like a password so you should have recovered it via email or on your phone if phone numbers are being provided . about campaign , i dont think they will be needing it because thier site already have an ad network service means they accept promotions too so why will they need to use someones service ? that will only make them small .
this is site is also more of a casino but they also have faucet , exchange , ad networks services . thats kinda unique and not all gambling site have all of this
