Does BTC tend to crash before the DJI?

Looking at the prognostications for imminent dire times in the stock market, and the matching ones / FUD for BTC, I was wondering how much linkage there is in the historical data.

And I wondered if maybe Crypto might be a "canary in the coal mine" for other financial markets, sensitive to the same factors but reacting earlier for whatever reason.

I do not find this analysis compelling by any stretch of the imagination, but it is interesting. And it does seem there is some synchrony if not mutual influence.
