And what if instead of $10 and $9, it's $75,000 and $1,000? And you live in an Eastern European country, where the former will feed your family for years.
Do we have the numbers on what percentage of disclosed bugs are from Eastern Europe/"poor" countries? My guess is that gray-hat researchers take into consideration their likelihood of being caught when considering the bounty.
It would be interesting to know the percentage of people from less-developed countries who choose to claim bounties rather than exploit the bug vs. that of people in more-developed countries. I think you would probably find that fewer bug bounties are claimed by researchers in countries with less computer crime enforcement. I think you would also find that raising the payout for bug bounties would affect that likelihood.
