Cryptocurrency-related lending has become a black smudge for the industry these days and according to a recent report, bitcoin's low price has put billions in mining loans under stress. The report, which quotes the co-founder of mining company Luxor Technologies, Ethan Vera, says that roughly $4 billion in loans backed by crypto mining rigs are extremely close to running a risk of default.

Analyst Says Miners 'Are Nervous About Their Loan Books'

The price of bitcoin (BTC) is 21% lower than it was two weeks ago and the price drop has hurt BTC miners a great deal. According to a report from Bloomberg, analysts say that a number of loans backed by mining machines are underwater.

Luxor's Ethan Vera estimates that around $4 billion in loans backed by mining rigs are under stress. "They are nervous about their loan books, especially those with high collateral ratios," Vera explained to Bloomberg's David Pan.

Using current BTC exchange rates, only 14 SHA256-based mining rigs are profiting with an electrical cost of around $0.05 per kilowatt-hour (kWh), according to asicminervalue.com statistics. The top mining machines manufactured by Bitmain and Microbt, gather between $2 to around $4.50 per day with an electrical cost of around $0.05 per kWh.
