Fed policy affects a lot of other financial markets, not just bitcoin, and there is nothing we can do against it. The only thing we can do is keep buying every time bitcoin drops in price and wait patiently. Despite the fact that inflation can last for a long time, it won't last forever, and at some point things will return to normal once again, so don't worry about the things we can't handle. The ongoing crisis will be a danger to many but also an opportunity for others. Opportunity or risk is only different in each person's perspective.
FED policy means money going in or out of the market and that’s why it impacts everything. If the rates are high, then there is a guarantee return on their investment so many wealthy people move their money into interest rate earning stuff. If the rate is low then wealthy people start looking for other things that could earn them a decent money.
Bitcoin is of course risky in either way when you have billions, but many people could still decide to invest if the rates are low enough. If the gold market, stock market, and many others are impacted by the decisions FED gives, then we are going to end up seeing that in the crypto market and there is nothing shocking about that.
