Due to quantitative easing and the printing of US dollars, this is asset inflation.
Unless the Fed tries to withdraw large amounts of money from the system to save dollars in the long term, real estate and stock markets will not fall. (But this is extremely unlikely)
Too much money at the top.
If they all buy BTC in U.S. dollars, the money still exists. Someone is selling these bitcoins. Therefore, it will be reused for other value assets such as real estate and stock markets.
In fact, the Fed will again increase its quantitative easing policy in the next market downturn.
Everything will continue to rise until the dollar plummets.
