good advice from all, but id like to suggest that one is very likely to lose betting $5 a pop, no matter what or how you bet. long term that is of course.

its just such an irrelevant amount you could well end up throwing $5 at anything and everything, perhaps not keeping records, perhaps not chasing value, perhaps not handicapping properly and other such pitfalls. who could be bothered doing all that to outlay a rather paltry $5 ?!?
higher you go up the $ ladder, the stricter/greater the focus.
