ONE question.

Can the USA take possession of all seized BTC? In this case, is it already the government's or does it need some validation?

People do not understand that the USA, being the 4th largest holder of BTC in the world, already has a huge reserve in its possession; if they are not obliged to sell, it is already a reserve.

Am I wrong in this thinking?

To bring down BTC without announcing it in the reserve, what is the intention, given that they already have a large amount in their possession?
