I mean, it's intentionally vague - but considering the source and his social network, I suspect the idea is that PG's trusted source has knowledge of some forthcoming challenge to the fundamental axioms of the current crypto ecosystem. Maybe there's some flaw in Eth's PoS implementation, or maybe Tether is going to collapse or...I mean, pick anything? How seriously you take this is kind of up to you. I personally don't trust PG one bit - nor do I own a significant[1] amount of crypto - so I won't change anything. [1] Like many people I have bits here and there from checking it out but nothing material to my overall wealth.
