Printing money for the express purpose of buying Bitcoin would be one of the most chad moves the Federal Reserve could possibly make. They're gonna suck & be hated for whatever they do, so why not buy some BTC at least?
As a Bitcoin maximalist I am finding it rather amazing you want the US government intimately involved in Bitcoin like this.
They're gonna be involved in it regardless of what anybody has to say about it. If BlackRock is involved, that means they are also involved.
