Documentation absent — unknown (2017)
BlockedCase description
A cloud mining operator that had been running since 2015 suspended all mining allocations in September 2017. The operator claimed profitability had fallen below operating costs, but provided no verifiable hashrate data, electricity cost documentation, or pool output records. Customers who had pre-paid for 12-month contracts had no basis to assess the claim.
