"The management of all projects do not want to list their tokens on any good exchange. Because there is a lot of management they just think of their own profit."
I really doubt this, because if a token is not listed on crypto exchanges, the project is dead when no one is buying and selling the token. So the listing is essential, it is beneficial for both the project and the exchange. However, the number of projects is larger than the number of exchanges and projects need more exchanges, so they are forced to pay fees for the listing, ranging from a few tens of thousands to hundreds of thousands of dollars.
