It’s very easy to determine his motive. He wants to have a passive income without risk on betting using multiple account with different platform. Probably he is a whale player that want to have an unlimited passive profit through this kind of scheme which we all know that will not will last. Sooner or later Stake will restrict his account VIP reward feature once there’s no betting activity on it. Stake will not allow anyone to continue benefit with their bonus system without having a chance to make a profit on the user account.
I dont think he is a whale as if he is whale, he will stay wagering in Stake and leveling up to get bigger rewards instead of trying to look for similar bonuses program in other casinos.
As we all know, the VIP program in Stake is not something like "guarantee", there might be a change especially if players are no longer active.
At least the amount of the bonuses will be reduced from time to time if player is no longer make any wagering activity.
Casino is a business, no casinos will give bonuses all of the time even if a player is having the highest VIP level but not making any wager for long period of time.
