there are many reasons why ICO fails, I think the failure of ico is due to the unsupportive teamwork in completing the ICO marketing especially when they want to cooperate with colleagues, the work team can not have a good experience and the product they produce is not interesting to sell.
Not really, it's mostly about the hype and advertising. Telling you, it's a tons of good nice projects on the market but nobody knows about them due to the situation that projects aren't presented anywhere
in my opinion, the main failure of ICO is a less interested investor. sometimes, they have a good and professional team, and a good concept. only investor interest in the project is still lacking. whether it's because of what.
