What it means for you
Big-picture stories: what this family of tests supports, in plain moves. Information only, not financial advice.
- Big-picture stories (inflation, the Fed, ETFs, altcoin season) rarely turned into a rule that beat holding.
- Bitcoin did move with risk appetite: in bad weeks for stocks it usually fell too. Diversification from stocks is weaker than the story says.
- Headlines explain the past better than they predict the future.
