The S&P crash coincided with the news about charges against bitmex. Also one of the people involved in the exchange was arrested, the others were not because they were outside the US.
There's nothing to worry about. Such news 2 or 3 years ago would take us down by at least 10%. The market is more mature and less volatile now than was a few years ago.
Bitmex is cancer and should go down asap. But then, there are so many cancers in crypto (like Tether. There are also others coming to surface recently.) It is impossible to fight them all.
Who would nuke another nuclear superpower? Only someone with a death wish.
China might not be as strong as you think it is.
Maybe the war has already started.
Somebody or some country engineered Covid19 and released it on us. Just because countries can't throw nukes anymore doesn't mean they cannot fight in other ways.
