I have few questions.
1) Has anyone bought this script yet?
2) If script is working, why you are not making money with it?
I would consistently create new accounts; once a 4BTC bank doubled, I typically withdrew; moved into a new account and started again.
That would imply that provably fair site is cheating

3) Why do you think it is important to move to new account(s)?
The buyer need only provide proof of intent (ability to fund); use me as the referal link (new account I'll set up), and keep their stats open; with a 5% commission on their proceeds.
This would imply that you are trying to catch naive whale to get referral commission.
4) Is there any other reason why someone has to sign trough your referral link?
