I don't think that Bounties and startup projects will stop as long as Blockchain Technology continuously adopts by huge companies globally. Blockchain-based Projects have different categories and the concept of those projects needs to develop for the sake of our environment and community around the world. Most of the projects give convenience to its customers worldwide and resolve some major issues faced by our environment. We need blockchain projects that will be truly beneficial to our society.
For Bounty Campaigns, this is one of the effective forms of marketing for startup projects to spread their brand awareness and acquire more users organically. Companies including those who conduct ICOs or IEOs want to penetrate the market and the best components of their marketing strategy would be bounty campaigns. I saw some bounty tasks are highly improved by hiring excellent influencers (either for content creation or youtube vlog) globally.
But the problem today is most projects failed to reach their goals especially its token demand and market price, and also the expectations of its users. In my own perspective, it is very important for a startup project to thoroughly evaluate their project ideas, monetize/fund their project and promote the project on social media channels. And lastly, implement the project in accordance to its roadmap and give regular updates regarding the project development to its community.
As long as there is a strong foundation (like proper management of funds and supportive community), Start-up Projects will never stop or die.
