But what do you mean by promising project? A project can be promising and still have a worthless token as a medium of exchange. There are many promising projects out there, but their tokens won't be worth much.
don't call such a project a promising project. indeed there are many projects running, but the development has no response from the market, that makes their tokens have no market value.
I call any project a promising project that brings about a product which is of value to people. That doesn't necessarily have to mean that the token is of value to people.
