There is a reason for people not to buy tokens. The price of many tokens falls down and people lost their money.
Only tokens of not very good projects fall in price. Tokens of a good popular project are always parsed very quickly.
I agree with you. But it is necessary to create demand in the token and make the project useful. If people do not need in project and its platform they do not use the token of the project.
In this case, the project will not have investors. Therefore, developers will have to run the project with their own money.
But what to do investors if team of the project do not want to develop a token economy and do not want to srart listing. They can do nothing with their tokens.
