It may sound weird but I am making good amount of money from gambling as I find it the most easiest way to earn bitcoins in quick time and I am sure most of the people will find it risky way to earn bitcoins but I am very much comfortable in earning with gambling.
I have seen many people who are earning a living from gambling so I think even you are one of them who is able to make regular money from it as gambling is not a cup of tea of everyone and most of the people will prefer to gamble only for fun.
