Airdrops, bounties, or tasks that pay in tokens normally do not take up much of a persons time, which is why hunters join literally hundreds a month. Out of those 100, maybe 10 pay something and the rest end up scamming participants. Out of that 10, maybe 5 end up listing, so you basically spend your whole month for 5% of the bounties to pay you and hope it all adds up to something that can pay your bills for the month.
Regardless, you spend 15 minutes per week per bounty if that, so buckle up and hope it's a good ride.
