by Tyler Durden Thursday, May 20, 2021 - 09:00 PM Blink and you missed the biggest crypto crash since last March: having plunged as much as 40% on Wednesday, bitcoin is up 40% on Thursday almost wiping out all its previous day's jarring losses, with ether up more than 50% off its lows. Which is good news not only for Tom Brady who BTFD, but for UPenn which according to Bloomberg was set to announce it received its largest ever donation in a cryptocurrency -- $5 million in Bitcoin to support the activities of a research center at its Wharton school of business. Naturally, the donation which was anonymous, would have been much worse had bitcoin failed to rebound.
