if tokens don't get a boost from the team, they will disappear over time. because tokens or coins that are difficult to develop naturally will become dead coins and no one wants to invest with them. but it is true that in 2018 many projects that gave birth to tokens or shitcoin.
For me, I see campaign on removing dead tokens from the market as medicine after death really, because the people that were hurt most are not the people that would invest after the ICO or after they have entered exchange, but the people that have already invested during their ICO, they are the real victims of these ICOs, and if we are trying to protect any group from scam, it should be this group of people.
That is why we must all make a collective effort to ensure that we dont promote any project that is bad for them to even get to exchange or market to continue to scam people. We have to make lots of research of them and try so much to take them out before they get registered; it is something that we can do if we take greed and desperation out of our way.
