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.
He could only said such thing because he is lucky on it, but I am sure that if he is just like most of the gamblers, that always losing most of the time, then he is going to discourage us to not gamble anymore, since we are just going to waste our money if we are going to continue like this, but since it is the other way around for him, then that is why.
If he is comfortable in gambling, I'm comfortable on the Signature Campaign, because I am sure that I could earn money in the safe way and in the sure way, unlike in gambling.
