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?
This is so stupid question, there is not just one developers there are many, why would they end their livelihood by stopping to mine Bitcoins. Every time a Bitcoin is mined they earn a good commission, so no the Bitcoin miners will never stop mining, do you have any idea of how good amount of money they make? So think logically why would they even consider this thought, so lock your topic.
