It is certainly possible to make $10,000 gambling with $1,000, but not guaranteed. Because you should never think about making money from gambling where you are too worried, because when you think about making money you are most likely to lose immediately.
This isn't for everyone though as you don’t start this experiment if you can’t afford to lose your bankroll ....that's just basic gambling principle... As a gambler, you should only gamble what you can afford to lose.... Once you have that bankroll, it should be dedicated solely for gambling, separate from your personal funds.
So let’s say you start with a $1k bankroll, that means you’re earning a decent salary if you can whip that up easily. That way, your main funds won’t take a hit if the experiment goes south. It’s definitely possible, but the real question is: are people actually willing to risk $1k on sports betting?
