The US Federal Reserve has (had) what amount(ed) to a printing press, associated with "working groups" a.k.a. PPT. However, major US exchanges themselves, whether stock, futures, etc., are far more regulated and mature compared to a bitcoin exchange. The manipulation to which you're referring is far more indirect.

We're going to see crypto markets go through many of the same lessons that traditional markets did and slowly relearn why we have regulation and insurance.
Sure the traditional stock market is heavily manipulated but there's enough cross competition there that it balances out.
