'Dewi Aries' and 'Bitinity', both of them received $40 for recent gameplay activity after reaching platinum II. I had also received the same amount after reaching platinum II. @ryzaadit, you had received around $50 after reaching platinum II. Perhaps, the recent gameplay bonus for platinum 2 is something around $40. I think that wagering, bet size or other thing doesn't have big impact in the recent gameplay activity bonus amount.
