Root Causes
London-listed Argo Blockchain (AIM:ARB, NASDAQ:ARBK) built the flagship Helios Bitcoin mining facility in Dickens County, Texas at a cost of $1.6M/MW. When BTC price collapsed 65% in 2022 and energy costs rose, Argo faced a liquidity crisis. On December 28, 2022, it announced the sale of Helios to Galaxy Digital for $65M plus $35M of loan refinancing — effectively transferring the crown-jewel asset to Mike Novogratz's firm to avoid Chapter 11.

1. BTC miners are levered hashprice bets
Their P&L is BTC price × network share × energy cost. Any two of the three moving wrong is fatal in weeks.
2. Selling the crown jewel avoids Chapter 11 but wounds equity holders
The Helios sale kept Argo alive as a listed shell but wiped out most equity upside.
