Are betting sites worth it?

Betting sites are very risky because there is a very high chance that you will lose every single cent that you have bet. It is even worse than going to a casino because the scripts on the site can be modified so that it ensures that anyone who bet on it will lose money. I would stay away from all of them if I were you even though the amount to bet is low and the returns are high.

betfair has a referral program that pays 20 euros per sign up - problem is I have paypal and they don't accept it from Argentina.
