Do not expect virtual currency to have payment functionality; it only possesses a part of the exchange function. Very few people will use commemorative coins to buy things. Its nature is the same as commemorative coins, antiques, game equipment, game accounts, paid software, and stamps. There is no need to doubt its value, as long as it can be sold and there are people willing to accept it. Even a bottle of air or a stone has value. #doge⚡
