Before some 5 to 6 months ago, I made 30 bitcoins above by just using 0.02 btc only. But I deposited 20 btc at a time and lost them all in Satoshimines. That was a really a bad day for me . Now I am just surviving on signature campaign . So I decided to encash my every amount I got in my blockchain wallet instantly whenever I received it.
can you give the method how you made 0.02 btc to 30 btc..

There is no particular method of winning on satoshimines. Everyone knows , gambling is just a game of luck.
