The tail isn't going to wag the dog.

The S&P 500 futures are cash settled, you don't see people in alarm that the futures will set the aggregate index price.

Gold has been ring-fenced, Bitcoin won't be as easy a target - you can't fake warehouse receipts that you have Bitcoin like you can rehypothecate gold.

Sorry @maneco64, but you're simply wrong on this one.
