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?
As what other people says, there are a lots of supporters and developers of bitcoin which is impossible to abandon the project. we cant see them abandon it at the same time so if 1 developers quit for his job then there's a lot more and also more aspirants to be one of the developer of bitcoin.
Bitcoin is a remarkable advancement, and not everyone knows.
in my country people do not yet know how to use Bitcoin.
and I'm sure the future is very bright, and bitcoin will be the world's currency and everyone uses it.
