Double bonus means just deposit and withdraws 2X amount? Because you never mentioned your terms to use that bonus amount.
Avoid depositing any amount in this site.
I just tried to register to find out about what you are asking for but surprisingly I get this message "multiple account detection with the referrer". Lol, it is my first time visit and register and I do not use any free VPN, I'm using my own private internet connection but it is detected as multiple accounts. What would be a good reason to create multiple accounts for this site while the site is still new and many fishy things here?
