Market goes down, crypto seems to go down with it. Look at something like 1-month BTC and 1-month APPL or something.
It's not supposed to be doing this. I think this is happening because it's become so easy to purchase that people now just have it in their "portfolio", basket of everything, and when they want to sell, they just sell everything, stocks and crypto. They are the same thing to a lot of people.
This means it is getting tied into the existing financial system anyway, even without specific "controls" like central banking.
