The global economy will definitely have to change, because it is currently driven by debt. A lot of large infrastructure funding
are currently funded by "toilet paper" money that are printed from thin air. Wars are funded with the same mechanism, so I
figure that will also have to change. Bitcoin does not allow "printing money from thin air", because it is mined at a fixed rate
and a preconfigured supply. (This cannot be changed or manipulated without majority consensus and most people who can
make that decision would never be incentivised to allow that, because it decrease the value of their own coins)
