Seems like a desperate move.

The IMF can't have anyone break ranks.
The (now obvious) desperation of central banks, IMF, World Bank and governments to put a lid on Bitcoin is testimony to it's success. They know that they made a mistake in ignoring Bitcoin for 15 years and they only realised how much of a threat Bitcoin poses to their debt based business models during the last cycle. At 1.3 trillion market capitalisation their gears shifted. Now imagine what a cap of 10 trillion will do or 100 trillion.
That's actual and debt free capital being taken out of their corrupt and broken world. I'd be desperate too.
