FTX, the Bahamas-based cryptocurrency exchange, has filed for US bankruptcy court protection. It said it owes its 50 biggest creditors nearly USD 3.1 billion. FTX said it owes about USD 1.45 billion to its top ten creditors.

In November, the exchange and its affiliates filed for bankruptcy in one of the highest-profile crypto blowups. This event left investors and about 1 million customers confronting total losses in the billions of dollars.

On Saturday, the crypto exchange said it had launched a strategic review of its worldwide assets. FTX is preparing to sell or reorganise some businesses.
