I don't believe that Gambling helps Bitcoin in anyway , If someone joins the bitcoin community just for gambling then sooner or later he will lose everything and probably leave the community.
People should see Bitcoin from another perspective and not only as a gambling or a Darknet tool.
Right man, gamblings are made for you to lose money. Maybe you will win a couple of time but it will be a time when you will lose all
you are right, thats why i avoid it at all costs, in my opinion it is better just not to do it in order not to lose a huge amount of money
