what would be the reason for this fall?
FED can do this by more monetary tightening. They are doing this since 60k from last year.
The Fed is trying to contain inflation, and they are slowly reaching their goal, they are not targeting bitcoin, bitcoin is not worth their attention yet, what bitcoin is experiencing this year is the impact bitcoin has to face. Because it is part of the world economy.
remember that even the pandemic did not hurt bitcoin that hard back in 2020
The moment the market started collapsing soon after pandemic got viral throughout the countries worldwide, FED started printing more to save the economy in 2020. Hence, the markets rebounded very smoothly despite the covid attack. But this time, FED is on a different mood, they dont care about the stocks for 2023 as JPoW indirectly said this in his previous speech.
The crisis, and inflation this year are mainly caused by the pandemic, meaning the government prints money during the pandemic to save the economy, and 2022 is the year we have to pay the price for that money printing. The Fed is still the same, they are not in a different mood, they cannot continue to pump money, but instead, they need to withdraw what has been pumped out, only then can the economy stabilize.
