Re: If they can print unlimited fiat, can they just not buy up all the bitcoin?
His theory, in reality, would only work if all major governments would cooperate (in the case the central bank in question is the FED).
Governments don`t need to work together
STEP 1) FED prints more money (like they do daily)
STEP 2) FED BUYS ALL THE SUPPLY OF BITCOIN (and my fucking peaches and cherries that I back with my time, lifespan and work FOR FREE!)
You still fail to explain me what happens with the fiat that the Bitcoin sellers which sold their money to the FED/central bank get. Only if the central bank buys all exchanges at once (!) and then retire them from the market (exit scam) the same day (!!) even those outside of its jurisdiction (!!!) then the sellers could not bring the money back into circulation. And they must bribe all judges in all jurisdictions where there are crypto exchanges which were bought with central bank money and didn't return their money to the owners (which will initiate legal action), or alternatively kill everybody who complains about not getting his/her money back from the exchanges (=all Bitcoin holders).
Otherwise, simply the money returns into circulation, and then you get high inflation, probably hyper-inflation, like many others wrote already.
