Argo Blockchain, a Bitcoin mining company, has requested that trading in its shares and unsecured notes on the NASDAQ stock exchange be halted until Wednesday. The beleaguered company, which trades on both the NASDAQ and the London Stock Exchange (LSE), has stated that it will make a significant announcement before the start of trading on Wednesday. Only its NASDAQ shares have been halted. The announcement comes as Argo, like many other mining companies, is taking significant steps to restructure its operations in the face of an uncertain future for the industry.
