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!
