At current BTC prices, it would take less than $100 billion for the US to purchase 1 million BTC.
Discussion
100 billion of US fiat would push the price up dramatically, the question is what price points existing holders are willing to sell.
Just think about how much the price moved from strategy buying 22 billion since the election, at the limit it’s 50 percent increase in price for 22b in buying.
One could argue to buy 1mm bitcoin you’d push the fiat price up orders of magnitude, not to mention if everyone knows the US is going to buy 1mm coin the sellers would stand back and we’d see multiple God Candles🕯️
