Core Scientific Inc (CORZ.O), one of the biggest publicly traded cryptocurrency mining companies in the United States, said on Wednesday it filed for Chapter 11 bankruptcy protection, the latest in a string of failures to hit the sector, Reuters reports.

Austin, Texas-based Core Scientific attributed its bankruptcy to slumping bitcoin prices, rising energy costs for bitcoin mining and a $7 million unpaid debt from U.S. crypto lender Celsius Network, one of its biggest customers.

Core Scientific said in court filings that it had suffered a net loss of $434.8 million for the three months ending September 30, 2022, and had just $4 million in liquidity at the time of its bankruptcy filing.

The company engaged restructuring advisers in October and has been negotiating with creditors about a potential bankruptcy filing since that time.

More than a trillion dollars in value has been wiped out from the crypto sector this year with rising interest rates exacerbating worries of an economic downturn. The crash has eliminated key industry players such as crypto hedge fund Three Arrows Capital and Celsius.
