The intelligence of Gambler will play an important role in this situation because the limitation was known by the investor then he will be successful at the end otherwise he will not get the success till he he knows his the proper investment limitation on gambling.
Most of the gamblers know what is in the future in terms of risk on their investments before goes into it. I don't think we are ignorant of the risk and reward if it went in our favor. I think before any one has in mind to invest into gambling there is a complete decision that I can lose all I have.
We are fully aware on the possible things that might happen ahead because before we do play gambling we do already see other gamblers outcome so we can really apply it on ourselves that's why making such decision still depend on you and since you started out to bet then you accept on the risk of losing money rather than gaining.No one should be blamed of but only yourself.
