imo you cant get whale under your referral. Whales actually dont want signing up under referral. They always prefer signing up directly and havent seen whale under referral.
It is still possible to get whales under our referral even though it is very hard. Not all whales prefer to sign up directly, some whales may come to a review site about gambling sites. So having a review gambling sites will make you have better chance to have whales under your referral.
Okay, but the chance is very small like its nearly impossible. Plus whales only play on the well known site and had established good trust all the time(ex. pd) and before doing a review of course you have atleast visited that site directly.
