Now can I ask you, did you ever won a huge amount of money on gambling?
Ah I see you have edited the OP now. Okay my bigger is to win £800 or something from a £20 bet. It was long ago. I was not even aware of Bitcoin.I won in total 0.5 btc on dice and bought a nice new bathroom from the earnings. So it can be profitable if you stop on time and set a goal.
That's some good win and planned execution. I am glad that you used the winning for something good.Do you use Martingale technique or there other tricks you use 
What is this Martingale technique?
