I do not think that bounty is dead yet. It's a fact that it is not as profitable as it used to be 5 months back, but it is not entirely a dead thing. People are still earning from it, as a matter of fact, someone shared a testimony recently of how he earned over $2k in a month and I do not think it is something people should entirely give up on.
Bounty is not dead, but getting $ 2 for 3 months of working on Twitter is a waste of time. You need to participate in hundreds of projects that you can earn 100$
