I've seen something interesting in Bitcoin history: as soon as somebody finds a correlation between Bitcoin price movement and something else's price movement (usually stocks, indeed), the market decides to prove it wrong.
I was at a dinner party recently and Bitcoin came up in the context of markets and the economy. Someone shared their theory that cryptocurrency markets were part of the overarching tech bubble that's been developing since the last financial crisis, as reflected by the Nasdaq.
I didn't think much of the connection at the time, but I'm certainly considering it now.
