It depends on how much fund is allotted to a bounty project. So many Bounties out there present only the total amount of tokens for the bounty. But if you look and convert it to dollar for example. You can see how ridiculous the rewards they are offering. It deceiving bounty hunters. Newbies are often suffer for this because they just grab whatever they can grab any opportunity to earn. So always be careful, some bounty can be a scam also. So join at your own risk.
