According to Crypto Briefing research, since 2016, Bitcoin has declined within 30 days after each of the seven instances when the Federal Reserve paused then resumed rate hikes; the median loss was 2.4%. The pattern currently holds, as the Fed raised rates in September, paused in October, and is expected to resume soon.
The closest historical parallel is 2018, when Bitcoin fell 42% between the midterm elections and December rate hike.
