The main thing this does is entrenches Bitcoin into the system.

For instance, IMF leaning on El Salvador against buying Bitcoin for their reserves seems silly at best and corrupt at worst. You going to sandbag a small country in a global accumulation race?

Even though this is only an EO which easily repealed with a regime change, after almost 4 years of Bitcoin working its way through Banking, Insurance, Pension, and 401k systems another ChokePoint 3.0 type operation will cause to much instability and loss of trust in US financial markets.

As for the pure buying and selling part of this who cares. I am way more interested in how they structure the custody. My dream scenerio is each Branch of Gov gets 1 key. The SCOTUS key is more or less like what Unchained does only used as a backup.
