Core Scientific Inc. gained a record 73% on Thursday, just one day after becoming the latest cryptocurrency company to declare bankruptcy. It’s a move similar to what Revlon Inc. did earlier this year following its own Chapter 11 filing. In mid-2020, retail traders caused similarly perplexing spikes in the shares of other bankrupt companies, including Hertz Global Holdings Inc. and JCPenney. The miner’s bankruptcy filings show that it has $1.4 billion in assets versus $1.3 billion in liabilities, distinguishing it from most bankrupt crypto firms.
