It’s the processing, and for some reason they don’t like to accept decent sized deposits from people who don’t use bonuses.
Case in point:
I played there, then left the account sitting with like a couple hundred dollars for a couple of months. Then I came back, played the money away very fast, and tried to deposit from usemywallet. They gave me a $15 deposit limit.
What nonsense is that? I had never withdrawn, never took a bonus, very occasional player depositing some $250 at a time. (Usually I played after a good number of new games had been added to check them out).
Since $15 are not worth depositing, I just left.
I would imagine most better players would just leave at that point.
I went to a vegas tech property and deposited through usemywallet just to see all was fine with my account – no issues whatsoever.
And yes I think Betus and Box24 as well as Sloto have their own processors.
Oddly, Pantasia seems to be doing better than the others, and from what I hear they are owned directly by Rival.
