Possibly because they're in New England where the sun barely shines, but more likely because they're totally clueless and going to lose money; that page says they have "a power plant capable of generating over 100MW of clean energy an hour," which is incoherent; power plants don't generate more megawatts of energy if you run them for more hours. New York is not really a well-known bitcoin mining hotspot, and for good reason. Though I guess the state does have Niagara Falls.

Still, who knows? Maybe they have some kind of tricky angle on the problem, like using bitcoin mining to convert earned income into capital gains in order to evade taxes, which might make their clients money even if the actual operation is unprofitable.
