Bitcoin will die. Same with any other currency, if there's no one using it, there's no reason for it to exist.
With no one spending Bitcoins, there wouldn't be any transaction volume. With the no one trading on the market, Bitcoins will be worthless.
I think bitcoin will be really worthless without any users. If there are no demands, then there are low price and and so low users. Wonder what will be the new digital currency that will hit better than bitcoin.
It depends if any digital currency prove its quality as bitcoins .Also the factor that if bitcoins are dump and no one spends how about other crypto's .We know that bitcoin price has a huge effect on cryptocurrencies now and being dump by its continues marking up of bitcoins price ,So technically if bitcoins are dump the crypto's will also be affected in the digital currency it will also dump .Bitcoins can stand alone i only don't know how about other crpto.
