We all know that cryptocurrency is a new entity of money. So if the project made a campaign with a huge reward if this project does't have vision or use-case or utility of course they will dump its while still have value. If not, Like elrond because of a lot of use case participant who participated in their campaign wasn't dump the reward instead.
Yes, and it certainly makes sense, because whoever the person is will still throw away tokens if the project doesn't have a good use case or the interest of people who are new to the crypto space and in the real world.
