I think most of the people and also the ICO believe that bounty is main reason for the dump of the coin. It is true in either way but most of the participants are scammers. They make multiple accounts acquire most of the reward and when the coin is listed on exchange they dump it. Most of the content have only views (PAID) and no public interaction but then also then they are getting huge rewards and aquire the reward of true bounty hunter.
FOR ME THE ICO SHOULD HAVE THESE CONDITION :
1) KYC
2) content should be checked nicely.
3) Facebook and Twitter accounts should be checked if they have real people or not.
These things will reward only the one who should get rewarded. I think fraud will be very less by applying these things.
THOUGHT - Only scammer and fraud people dump their coins but True bounty hunters support the project by HODLING as they know how much it takes to give a good content.
It should indeed be a good idea in bounty, at least rules and also clarity. But will it work well and ensure that the project will be successful? Many participants have worked for weeks and at the end of the project they do not get tokens for various reasons and changes. Is that fair? The main thing that also needs to be considered is honesty in everything, for the appropriate results desired.
