Bitcoin will live in the future too and bitcoin will improve its system for future too but bitcoin will not be only one in its sector there will other digital money systems too but it is not mean bitcoin will not leader in digital money sector .
There are already a lot more digital money systems beside bitcoin but they cannot cross bitcoin because all of them all dependent of bitcoin so the price of bitcoin decides their future, if bitcoin is high so they also can be quite high if bitcoin is low they would be worthless, that is the reason why bitcoin will always be the king of digital currencies.
