Idk what makes you think this is going to happen given how the Republican Party has embraced BTC. Add in that the idea of registering BTC is hilarious for a country that doesn't even require you to register guns in some starts. Do you think Texas and Wyoming would go along with this?

Plus the US government already has a metric shitload of BTC for previous seizures so why do they need more? The answer is they don't and if they wanted to sink the price they could but it would slaughter Wall Street. Imagine the economic turmoil that this would cause as so many companies that are now dealing in this get hit with this blow.

This isn't logical at all I mean its not even good fantasy because the damage it does is much greater than whatever good would come of it and again Republican State governments have been passing laws to prevent this why would Republicans in the Federal government suddenly flip? The answer is they wouldn't it isn't in their interests as their consistents would be up in arms and so would their donors.
