Bitcoin soars as the Federal Reserve raises the key interest rate
This is both wrong and completely irrelevant.
First of all bitcoin didn't "soar", it just went back up a little. It has been doing that for some time now.
Secondly FED's interest rates don't really affect bitcoin price. Example is in May when they increased it while bitcoin dropped from $38k to $25k.
Inflation has probably been the most significant difficulty
Money printing is the problem, inflation is the result. In the past couple of years ever since COVID began, they've been printing US dollar non-stop. It was inevitable to see high inflation.
