Bounty will exist as long as there will be a competition in cryptocurrency. I also feels the same way and getting disappointed how most ICO ended. Most of them are having hard time reaching their softcap, extending their ICO and their bounty program. In the end, we are giving so much time for a cheap and lesser reward. Ofcourse, there are still profitable and got a potential ICOs but they are very hard to find. We can't blame these ICOs and bounty programs since the market still on the correction process.
I didn't blame these bounty. I just blamed the bad root. I think it is caused by too many scam icos and unrealistic projects. Now the biggest problem with blockchain development is that there are many concepts, but implementation rarely.
