Buddy, whenever I start playing a new game on satoshimines with 500 bits, I opened more than 15 boxes in a single game. But after cash out from that game , it shows me that I would have opened all boxes. This happens to be most of the time.
I have also made a lots of profit from satoshimines and won 30 + btc using 0.02 btc only but as usual bcoz of greed which all gamblers have it , I lost them all.
