True, bitcoin is one and only one and nobody cant stand him at the moment. And yes, bitcoin is the king here and it will be for a long time but there will be an end for him cuz every king dies eventually, you know what Im saying ? And someone will take his place , it could be any altcoin .
it doesn't matter to me what if altcoin is able to shift the value of bitcoin. if that is true then there will be an interesting competition between bitcoin and altcoin. My principle is that the highest value of my coin will support.
