Ah, YES. That's what it was. Margined accounts blowing up. Well, I for one am glad to see it! People doing margin with crypto are only serving as a crypto tax man for little people looking to simply invest by extracting fiat dollars from the crypto world, and that's not what it's there for. So good riddance to 410,000 accounts. Their getting flushed out and liquidated has created a great dipping buying opportunity for ordinary crypto people and I bought more last night as well.
