Bitcoin market cap potential and central bankers

In the latest price run to past 6k, volume was driven by Japan. 57% anyway.
GDP of Japan is roughly $5T, ranking 3rd globally
China 12T, USA 19T
Global total GDP is 78T with 127T in purchasing power.

Point being, if the 3rd place country can drive bitcoin to where it is, imagine the potential of the other 73T in the world.

So central bankers are a shady bunch. They love the power to print money and make loans to 3rd world countries.
The power to control the worlds largest economies. As (or if) things shift to decentralized currency, or bitcoin. At some point these greedy bastards are going to want a piece of the pie. They thrive on people, groups, countries owning them money. It's how they enslave, if you will, the world.
So what happens when Bitcoin starts to encroach on this? My guess is that they will print money or take on debt to buy a significant stake in it. They'll have to if they want to keep control, loan it out. And they have the $$$ to do it....for now.
When is that day? It's when they realize bitcoin is being used, here to stay, must be controlled or manipulated. I would guess 1-2T in market cap. Somewhere between 50-100k per coin.
