Binance CEO Changpeng “CZ” Zhao shared what he said were two big lessons after confirming earlier in the day that FTX had agreed to sell its non-U.S. assets to the rival exchange amid a liquidity crunch. 

"Never use a token you created as collateral," he wrote on Twitter. "Don’t borrow if you run a crypto business. Don't use capital 'efficiently.' Have a large reserve."

He said that Binance had never used its BNB token for collateral and has never taken on debt. The news earlier in the day triggered a broad selloff in crypto markets, as traders worried about broader contagion. 

"Stay #SAFU," he said, referring to a term used by crypto enthusiasts to denote that "funds are safe."
