The DCMA ( Digital Currency Monetary Authority ) announced the release of the Unicoin at the end of last month. This is intended to be the supernational digital currency unveiled by the IMF, and it is intended to incorporate it into the SWIFT payment system ( well that's what the blurb seems to imply).
Although I do not doubt that the whole project will be launched, somehow it seems to me that not even all the machinery that the IMF owns will create anything important from all of this in the sense that the coin will start to be used by the masses. According to what happened in the past, it is not so important what it is actually about, but who is behind it. Let's just remember how much hype FB Libra achieved even when it didn't officially exist, but it had a platform of 2+ billion people to whom it could sell its project.
So how will this affect Bitcoin? Obviously Bitcoin is an alternative to the government control via payment restrictions. The government can't stop Bitcoin directly, and restricting exchanges with the fiat system could lead to an alternative payment system to the detriment of the national currency. I believe that government agencies and banks have been buying large blocks of Bitcoin to restrict its supply, and to create volatility. They will probably continue to do this to make it unattractive to businesses.
What can we do to help stabilise Bitcoin as it enters its first stages of maturity.
Little or not at all, because the concept behind Bitcoin is completely opposite to what the IMF and the like offer. The IMF and similar organizations obviously want digitization in their own way, and it is quite legitimate for them to try, time will show how successful they were.
As for the idea that there is some secret agenda of buying BTC in order to harm it, somehow it doesn't seem to make much sense to me. If that were happening, someone would already notice such things, because not all countries work with black funds that hide their tracks. If someone powerful enough wants to harm BTC, then they can do it in a much simpler way through laws that cost them almost nothing but ink and paper.
