As I mention in the article in Spanish, I say it again. It's a good alternative as you say to generate extra money, but how lucrative it can be, (and I'm not talking about becoming a millionaire) here I mean the cost value of the time you spend playing the game and the money that is generated by that time. Is it worth ? ... Of course some have made this a profession of it ..... but the common one that needs an extra entrance of money ... will be profitable ????
