"such coin or token grow in price value as number of people join the project which made it to be autonomous"
Does that mean the project has absolutely no advantages in terms of technology & solutions for the ecosystem? Is project coin used only for basic payment like Bitcoin?
In 2017-2018, such a project may be successful because there are not many competitors, but currently they will be destroyed because users will not trust such new candidates. We already have Bitcoin and their hardfork, then DASH, Zcash serve as a means of payment and storage of assets, we do not need other coins if they are not better enough.
Some of the tokens of the IEO projects have been listed and appear on coinmarketcap but their future is not yet safe, so there is no room for the projects you mention.
Their future is only junk coins.
