bitcoin is maintained by core developers, would Bitcoin die a natural death if the developers no longer exist? Or if they stop maintaining/developing/upgrading the system?
There are lots of developers that can take their place in maintaining, developing and upgrading btc system. There's no way btc will die even if the pioneer core developers no longer exist. Besides, how will those developers thay cause hardforks do some upgrades if they don't know how btc system works, right?
