I suspect the bankers (and their constituents) since they can create as much fiat as they wish to buy. Their magic paper is the barometer that is used to measure the value. The government has had an interest in our using crypto more than a decade before Bitcoin was invented for the purposes of enticing us to use the internet for commerce. Without writing the future post I have planned, it seems obvious to me that those with money play with the value being attached to the crypto field.
