The point here is very much clear to every sensible man. You give free money ? No, you used this platform for your promotion.
I have cashed out 0.01 btc as  I have already mentioned. The point when I cashed out there was 0.0005 btc left and it was not deleted by you nor there was any mention of confiscating winnings over particular ammount.
So you have to assumed that I played with my own funds and won 0.006 btc which I demand you to send to my wallet which you have just posted.

Note: You can not make new rules as per your wish and apply them retrospectively.
