Online gambling has increased addiction very rapidly. It's easier then ever to jump out of bed, go on yourlatop and place a few bets. I have a few friends that are heavy gambling addicts and they all ended up in debt and had their lives ruined. I'm not completely against gambling but lets not forget how dark it can be.
They should not start gambling without proper knowledge though...
They have the knowledge alright if we will be talking about the gambling game, it's rules and the prize or profit they will be getting if they win but the problem is that they don't know one thing.
That one thing that is so important, their knowledge to what may happen in the near future. Gambling may be enjoying, may be entertaining but when it comes to the wasted time and money you risked for that, it will make you regret.
