We all know the US gov rules, dictate to rest of the world.
So if they cornered the btc market, afterwards the btc price could only go up, factor with this a few btc friendly directives, and a massive coup would have been achieved.
What is the downside?
I don't see any reason why the US will buy a trillion worth of BTC. Just to have the power over the BTC market? Is that what you mean? And they are to go friendly to BTC as well. And then a coup would ensue. That would be the best thing to happen to us. But it would be a suicide to the government. The true rulers of the world, the billionaire bankers, would see to it that the government will not do anything stupid about this issue. Otherwise, government positions and even life could lose.
