US is planning to buy 1.000.000 BTC for it's strategic reserve. Other contries are accumulating as well. When the accumulation will end, I can imagine the price will be driven to 1 Million USD per Bitcoin, with a lot of printed $.
There is no official information that the US is planning to buy 1 million BTC as a reserve. This is just the idea that Senator Cynthia Lummis raised at a bitcoin conference in Nashville, in July 2024.
To date, no country has officially had bitcoin reserves and is actively accumulating bitcoins. All is just rumor or is under discussion and waiting for National Assembly approval.
Also, if countries plan to buy bitcoin as reserves. They will need to use sources of funds such as borrowing, issuing government bonds or selling other reserve assets to buy bitcoin. They won't print money indiscriminately just to buy bitcoins because that will cause inflation. So this is going to be a long process.
