The US could definitely buy a lot of Bitcoin to hedge against loss of purchasing power (which has been done because of their reckless spending, money printing & fiscal policies). Will they do it though, I am sceptical. The last I saw, the US was selling large amounts of Bitcoin that they had stolen confiscated from Silk Road & other illegal schemes.
Can you even hear yourself, the US should buy a lot of Bitcoin to save the economy? Many of you will not stop to amaze me, why talk when you do not have anything good to spit out? If you must know, there are good and valid reasons why countries' governments will never own Bitcoin, legalise it as a legal tender or have a sizeable amount of it. The reasons are in front of all of you but you are turning a blind eye to it or you just don't care, nonetheless, for the government, the risk is just too much for a nation. Leave Bitcoin for us the citizens and leave the government alone.
By the way, what backs Bitcoin? And what would happen to the government funds and the country if anything unforeseen happens to Bitcoin? Do you know the future or has it even helped the economy of the countries who bought it yet?
The US government can't gamble the future of the US with Bitcoin and there are many packages already yielding for the country. The US government owns many assets already and Bitcoin is just like any other investment, so what is special and why must they buy it? Is it to save the US economy, how? This can only get the government richer, not the citizens, so which economy is it helping? I can't even stop thinking why a person would write such without thinking it through. Go and learn economics, commerce and investment maybe you will know the gravity of what you wrote.
The US is a very rich nation and the government is trying its best and doing everything possible for the economy. What will help the US economy are policies, not investments/government's money. Leave the US citizens for the investment part and let the government focus on the policies. For the record, the US citizens already own a sizable amount of Bitcoin, so why the government? You are so funny!
