I would be worried about how thin the market is though, as each significant price increase seems to relate to a specific piece in the online tech press. In that way it has a lot in common technically with a pump and dump scheme. As long as you're running a small enough farm I suppose I wouldn't worry too much about it as long as you're philosophically good with the increased energy use.
