mpicpp (3454017) points out this story illustrating the problem of betting on the differential between the price of deliverable bitcoin-mining hardware and the price of bitcoin itself: Yet another Bitcoin miner manufacturer, CoinTerra, now faces legal action for not fulfilling an order when it originally promised to. CoinTerra is the third Bitcoin-related startup to face litigation for breach of contract and/or fraud in recent months. The CoinTerra lawsuit was filed in late April 2014 by an Oakland, California-based man seeking to be the lead plaintiff in a proposed class-action lawsuit. Lautaro Cline, the suit alleges, purchased a TerraMiner IV in October 2013 for delivery by January 2014. The company promised, he claims, that this miner would operate at two terahashes per second and would consume 1,200 watts of power. It did neither. However, Cline's suit also claims that CoinTerra did not deliver the miner until February 2014, and it "operated well below the speed advertised and consumed significantly more power than CoinTerra represented, causing Plaintiff to suffer significant lost profits and opportunities."
