My greatest gambling victory is still at pd. I turned faucet(1551 sat) to 1 Bitcoin in a week. Nowadays I try the same method at betking with higher payout. At PD I played 9900x payout and hit it several times. Since betking has higher payouts than PD I play at 99000x and hopefuly will hit it soon.
That's a good strategy, you are not risking anything on that, you just have to spend a little time in order to claim your free coins, I will try that now at the betking as I have not sign up on that site yet. I wish I could have that luck as you are as 1BTC is already a decent amount for me to spend for family vacation.
