I think maybe some in US underestimate how much Bitcoining is going in the world outside the US... a lot, an awful lot, even though China has officially thrown out the last batch of miners, they absolutely missed a lot. Those who did leave are already being replaced.
And now some countries are taking to using it as their national currency.
Rather than try to destroy Bitcoin, it would make much more sense for the Fed, and all other countries and banks to make sure they keep a reasonble stock of it, for when the dollar, and pretty much all fiat currencies collapse in value relative to it, as is happening even with gold. If you don’t believe that, have a look at the long term average of bitcoin/oz gold, gold is on an elliptical curve which began positive, became level a few years ago, and is now on an increasing slope downwards, a clear elliptical arc.

That doesn’t mean the end of fiat (Though it might be for gold), only that it will come to be valued against something else; the live flowing energy of sunlight.

I still stand by the assertion that money is moving from money-as-debt, to money-as-sunlight, and Bitcoin is the gateway that it is all hingeing on.

Each bitcoin punches a hole in the old zero-sum box, through which the sunlight shines, a whole MW of the power from it, per Bitcoin, which everyone may use to generate their own proof of work tokens, which will complement all of the other currencies and shares offered in the market.

Not long now.

Another very simple way of looking at it, is if they could have killed it, they would have done so by now.
