were they projects in the first place? That should be the first question to ask if those projects were ever established. Some Icos just raise the monies from investors, share the tokens and the team disappear into thin air. In that case what it means is that they never developed the said product in the first place. So the token will slowly die out of the market as quickly as possible since there is no product backing or a team to push the product forward. That is what is happening to most of the projects after ico.
