My main focus is on multiply-BTC in freebitco.in
After I collect 0.0002BTC on it, i am planning to use it with starting bet 1 Satoshi, and martingale method. Since my laptop is on almost all the time, and I think it can afford a single-tab browser with the Script running, even while I am doing other work.
Freebitco.in is good only as a facuet. Their house edge will madden you once you play on other dice sites like 999dice or PrimeDice or Rollin or FortuneJack. Also, martingale? PM me and I will offer you better strategies for free.
Well, I am keeping hold on gambling for now, but would like to know other betting strategies.
Thank you all for your feedback.
