This makes me remember Tokoin and tachyon protocol bounty campaign, after hunters are paid they made huge profits from this bounties and still the value are rising and not dumped, so my question is why are other bounties getting ruined after launch? Or after hunters sell their rewards? Probably because they are bad projects, hunters aren't to be blame here isn't it? Good projects will never dumped because hunters sell off
There are lots of reasons as to why a project is likely to fail. There are lots of scam projects, and it's true that it might have affected ICOs in some ways. Another thing that can lead to the failure of an ICO is when the project fails to reach its milestone. There are times when the organizers fail to do the right thing. Some of them fail to register their websites and accounts, and thus may lead to hackers taking over their website in future and leading to them losing a lot of coins in future, which will in turn lead to the end of the project.
This way bad projects are just becoming part of this crypto space and it is individual's responsibility to take care against those bad projects and no one could do anything else. Just doing all the due diligence may save an individual investor. This the reason I have stopped contributing to ICO some long time back itself and never touched any IEOs as well.
