It could be that crypto will directly benefit from a stock market pop. If even 10% of that capital ends up in the crypto market, we'll see an institutional driven bull run that makes the previous retail bull runs look like a joke.
okay, but why?
in a stock market crash scenario, i think it's more likely the opposite. we're talking about a huge economic contraction, and crypto is absolutely not a "safe haven" with its < 10 year history and beta software status (which still occasionally has major bugs).
when credit is easy and the markets are bullish, institutions might pile into high-risk markets. not really so during major contractions. i'd love be proven wrong on that though.
