The current establishment will want to maintain the dollar as long as possible. Doing so will make the transition (that they seem largely unaware of) much smoother.

There is a huge demand for dollars internationally. The fiat system had no simple means of filling that gap until stablecoins.

Tether could tank one government currency after another until the whole world has transitioned to bitcoin.

Perhaps that's an overly optimistic take, but with the current variables as they are this seems the most likely outcome.

In the meantime we need to focus on the open source freedom tech that helps us escape the walled gardens. (Preaching to the choir there)
