I think the ICO season is not over yet, so you will be able to earn some cash with Bounties but not like in the past..
So enhance your knowledge now because you have a lot of free time

The good projects now do IEO instead of ICOs. So it is very difficult to find good projects that pay via bounties.
I am not sure if those project who do IEO spend a lot of money in bounties as they main marketing strategy happens via exchanges.
