What are possible white swan events that could help us reach the stars?

We often talk about black swan events, which is an "unpredictable event that is beyond what is normally expected of a situation and has potentially severe consequences", such as COVID19. We have definitely had some of these.

But what about possible white swan events? Which events could cause crypto to explode like it has never done before? And how big would their effect be and would the effect be short-lived or sustain itself?

I suppose one event might be Ripple winning their SEC lawsuit? Another one could be a major company buying a truckload of bitcoin? What about the Bitcoin ETF we have been waiting for?
