Do you think I should set this $10-$150 offer without id check requirement?
I can't say which is better but "big risk, big reward"
If you can't afford to lose then you should check their identity, would be good if you check their identity not so detail (just some things you really need to check)
How can I check my customer's identity if I should at all? There are people who can in fact "sell" their identity to his partner, register accounts for themselves, and give him control over it. My checking procedure is just senseless against them. But having my own accounts blocked for suspicious transfers is not good as well.
You are right, but at least you have an effort to avoid yourself from become a victim to scammers. Not all scammer is smart enough, by checking your customer identity you can assume that you have eliminated those stupid scammers.
