an important question for me, that no one answered: whoever creates a coin owns it or is it jointly owned by the community that uses it? technically or legally?
If the coins already sold to the public, I think it is not owned by the developer anymore since they cannot control the user anymore. All they have to do is to buy back the coins or to make no progress on their project. If you bought tokens/coins you are the new owner of it so you will be the one to decide whether you will hold it for long term or you will sold it right away.
