For this time anything can happen. but I think that the world will switch to another payment system, the world financial revolution will take place
Around this time, many countries will have already converted their physical
monetary systems to digital systems, likely using editable ledger systems.
They will not be public, immutable, decentralized, or etc, and will not be
utilized for the purpose of a more efficient and fair monetary system, but
to assist and ensure governmental control and monitoring of their citizens.
Under this system, purchases are recorded and analyzed instantly to
determine the human's probable future actions.
Based upon this system, in conjunctions with a synthetic implant powered
and secured by the human's nervous system shortly thereafter, it will be
possible to implement an end game scenario where human rights no longer
exist since they can be denied by erasing your existence from their system.
In those countries, citizens who have been "erased" will be unable to even
buy a loaf of bread or be given access to medical service facilities. Any
citizens who come across an "erased" will be accused of unlawful association,
and thus be subject to possible removal from their system. This reinforces
the government's power and control over the human citizens. The humans
in this system can never collectively organize and attempt to overthrow this
totalitarian control system since their future actions are calculated based
upon their recent actions and recent inactions.
At this time, the Bitcoin Network is the only free and fair montary system
that allows humans to survive outside of this future totalitarian system.
Majority of individuals who have been "erased" will form small collectives
which perform services that are legal or deemed illegal by those counties,
and will be compensated through bitcoins. Citizens within these countries
will at times need the services of the "erased" and so some will possess
bitcoins in secret so that they can purchase their particular services.
Governments will put on a big fight before accepting bitcoin's superiority in my view. I don't see how you are going to convince the likes of Jamie Dimon to convert their assets into Bitcoin. Also have on mind that Jamie Dimon may run for the presidency of Federal Reserve and this may lead to him trying to convince whatever president of the US at that time to deploy a big attack on bitcoin. We will of course survive, but it may be a war that lasts years and causes a big market price.
Let's hope that the smarter bankers that see the opportunity of being bitcoin friendly instead of anti-bitcoin take the lead and we all get rich while enjoying the technology that bitcoin brings us without any additional drama from old dinosaurs trying to fight an asteroid.
