I'm not entirely sure that online gambling is illegal in the US. I think I read somewhere that there are no laws saying that it is illegal. It probably is, depending on the state? So before you try your hands in sports betting, make sure to do proper research about the legal issues and becoming a responsible gambler. In other countries like Australia, it is legal; I don't worry about being jailed for online gambling and checking http://au.freebets.com for sporting events.
