Recently, information appeared that there are about a thousand dead coins. Probably, this number is too exaggerated, but now there are a lot of such coins and tokens. It should be said that it is not worth while attributing your cryptocurrency to the category of useless and throwing it away if we are absolutely not sure. The development team may have its own different difficulties with the development of their projects. They can earn again after a considerable period of time. Therefore, I prefer while keeping my cryptocurrency in wallets, even if the projects of this cryptocurrency seem to be dead. Time will tell how dead they are.
