This is perhaps the easiest and the quickest way to lose your money.
I simply gave the option to the OP if underage then answer is no. And if above 18, and have some pocket money left then can try the risk, if make money you can go and if you lose that money then forget the trips and all. Then you have to sacrifice it.
There is no need for such sacrifice. In sports betting you will really earn some but there will be more times that one shall lose money on it.
Especially if OP is just new to it and wanting to try. Nothing bad to try it but it is hard to do it as a means of income. It should be done when he has his own money and would love to bet on the matches he thinks can take advantage.
