Hello,
If you wanted to make 50 Dollars a day what betting strategy would you take?
The "no-betting" strategy
Hehe, in other words, you are suggest OP to get a real job and do other things beside betting such like, trading.
I would prefer to play it in slot machines and dice games. And $50 is too big also to use in these games everyday so I would use it for sports betting might help the chance to profit my $50 everyday.
Both of slot machines and dice games are games based on luck, I think it would be hard for you to earn atleast $50 in a day.
