I have not spend that much time on gambling because I know that most people lose with gambling and the same things is going to happen to me and that is why I do not gamble much.
Of course I have gambled some times but not more then twice a month.
Me I am doing gambling twice a week. Atleast it takes 2-3 hours for doing gambling. Well it is 8out of 10 winning chance in my statistics. As for I am betting or playing dice site or satoshimine. Its either the two.
