According to Bloomberg, the crisis engulfing Sam Bankman-Fried’s FTX.com is rapidly worsening, with the onetime crypto wunderkind warning of bankruptcy if his firm can’t secure funds to cover a shortfall of as much as $8 billion.

Bankman-Fried informed investors of the gap on Wednesday, shortly before rival exchange Binance abruptly scrapped a takeover offer. He said FTX.com needed $4 billion to remain solvent and is attempting to raise rescue financing in the form of debt, equity, or a combination of the two.
