If you didn’t know, a cryptocurrency exchange lost $1.5 billion recently.

How the Biggest Crypto Heist in History Went Down [The New York Times] – “On the night of Feb. 21, Ben Zhou, the chief executive of the cryptocurrency exchange Bybit, logged on to his computer to approve what appeared to be a routine transaction. His company was moving a large amount of Ether, a popular digital currency, from one account to another.

“All of the Ethereum is gone,” he said.”
