The final floor of btc will be zero, fact, when? who knows
It looks like you need to check what the actual definition of "fact" is. Bitcoin being zero is very impossible. It can significantly crash down to probably even 3 digits, but zero? Too unlikely.
BTC has so many glaring problems, and CORE has refused to address, in fact the community just forks every time there is a conflict, this is called 'tower of babel' and never ends well.
Can you name some of the problems you're referring to?
Bitcoin is open source, hence there are no centralized authorities to do the deciding. Forks are inevitable.
