In my own opinion I think that other coin move fast but bitcoin moves faster than all. I can say that because if those other coins move faster they must be the top of all among the crypto currencies now days. But we all know that in this very moment still bitcoin is on the top which only means that bitcoin is the fastest of all among coins. Bitcoin users always hope that bitcoin will not be replaced by others because if that time come surely some of the users of bitcoin will shift to other coins.
