Kodak's attempt to ride the cryptocurrency wave isn't limited to offering its own virtual coins. CES attendees have learned that Kodak has attached its name to a Spotlite-run bitcoin-mining business that will lease you a Kodak KashMiner computer for a two-year contract. It'll cost you $3,400 plus half of the value the machines earn, but Spotlite argues that it's effectively a license to print money. If you believe the company's math, you'd be paid $375 per month if bitcoin maintains an average price of $14,000. However, there's just one problem: The math ignores the very nature of how bitcoin works.
