There must be something valid in the theory and practice of Bitcoin as an alternative to western currencies. If not, the Fed would be in NO REAL RUSH to push through a digital USD Currency. But yet, the Fed is pushing it through very hard and quickly. I think the Fed knows very well that most of the recent volatility (since 2014 at least) has been created by itself and major wall street firms in an attempt to crush its stability
This type of conspiracy theory is why conspiracy theories get a bad name.
Adults look at Bitcoin and say "hmm, that's actually a good idea, how can we do the same?"
That's really the extent of how much Fed has thought of Bitcoin.
