Whales gamble using large amounts of money, so the thing that Pope prioritizes the most is a large, trusted casino with a good reputation so that the money he deposits for betting can get a guarantee of security.
Be careful when you are using online translator, the one in bold above should not be Pope as I believe you mean to say whales.
When you write Pope, it refers to the head of Catholic Church and it is not good to see/read it as it sounds like you are connecting Pope to gambling activity.
At least double check the result of your online translator first before copy and paste it in this forum (you did a bigger mistake before this one in other thread).
Sorry for out of topic.
After all I'm sure the whales already have casinos that they rely on and trust i so to get whales when doing affiliate is quite difficult and almost impossible.
Agree that it is quite difficult to get whales as our referral, but if you have great resources such as a youtube account, website, or other social media accounts with great number of followers, the chance to get whales is open although there is no guarantee.
