I think this is possible but not feasible. Some ICOs maybe scams but not all. And investing in them is your prerogative and still it is you who decide to invest or not. In bounties however, you are not investing in anything but is rendering your services in the hopes of getting a reward later on. Even in normal companies not related in crypto, investing in a business or idea does not guaranty you of a nice profit. Most of the time, they would end in losses or closing the business altogether. This risk is inherent to any business out there.
