Fed Funds Rate
US base interest rate set by Federal Reserve: world's most important rate.
Fed Funds Rate: USD price of money. High (5%+) = money expensive = capital prefers bonds (crypto bear). Low (0-2%) = cheap money = capital chases risk (crypto bull). Markets price cuts 3-6 months ahead.
In plain words
The interest rate set by the US central bank. High rate (5%+) means safe USD bonds pay a lot, so capital flees risky assets (crypto). Low rate (0-2%) pushes capital into risk: that's when crypto pumps hardest.
