My main point is that the main blame does not lie with the developers, but with the users. There are many grooms who specialize only in farming airdrops. They do not care about crypto, they do not care about the tokens that they are receiving or the project. They only care about selling it. They are the ones that have ruined it for most others.
I understand your point and in fact some projects who have failed in the past is because of Airdrop and bounty Farmers that plague the projects and getting tons of coins waiting to dump it when the coin gets listed on exchange, this have cause a lot of projects failure in the past, so we need to point that out in this discussions also.
There are many projects that use tokens for marketing, especially organized marketing such as Airdrop or Bounty. In these, a large amount of tokens are distributed and when that coin is listed on an exchange, all the hunters start dumping them on the market. And due to the excessive selling pressure and listing on small exchanges, the liquidity is very low and that coin goes down in the market. And the team does not have the capacity to back up that coin. And all in all, that coin crashes very quickly.
