I think gambling will became profitable if you play gambling games that you can analyze it. But it is really depend. Most of the time gambling is not profitable, for me gambling is dangarous, so we should be careful everytime we enter gambling.
Yeah, gambling can be a profitable activity, but i don't think it will good for long run. Because it will make you become greedy and you will lost control on yourself.
Yeah, it's something that can not be closed again. because gambling is one of those places that can give you an advantage, but it also will not give you a good advantage to those uninitiated or is not yet know how the game goes. So gambling benefits only to those who understand how to play and gambling is not the place for long term profits
