The best Bitcoin Gambling Site and strategy is in my opinion the following.
     
    You can claim free Bitcoins and Doge to play.
    Every 5 Minutes you can get 200 Sat BTC or 0.2 DOGE
     
    You can claim this until you have 999 SAT and/or 0.999 DOGE
     
    My way:
     
    Claim the free amount 5 times.
    Then just go the highest risk way... double, double double ...
    If you hit it ONLY 6 Times, you can withdraw.
    Thats 0.00031968 BTC. And its really not hard to double 6 times. You can double this again .. if you hit it another
    4 times you´ll get 0.00511488.
     
    I made with this simple strategie more than 0.5 Bitcoins in 2 Days.
    And when you made it, you can make even more by playing other strategies with your won BTC.
     Try your luck!
