I think i gamble for the same reason many other people gamble, for a chance of profit.
I also watch people on Bustabit winning & say "well this isn't too hard". Then when i try it, its extremely hard.
You shouldn't use gambling to search for a chance of profit because you will feel that it is too difficult to get. You will better to search for the other way for making a profit such as you can do trading to make a profit than to use gambling. You already try it, so I guess you have the experience of making money from gambling, and you should not continue to gamble for a chance of profit.
