I dont find bitcoin as useless thing, if you will just appreciate things that can bitcoin provide for everyone you will see the importance of bitcoin existence. For my self, bitcoin helps the community a lot, imagine, if there is no cryptocurrenc, I as a poor person cannot have my own bank, and cannot even find a work, bitcoin is nothing to do to a middle man like government does. Bitco8n is a chance for everybody, people are being coonnected around the world.
