What is butterfly labs?
They sell "bitcoin miners" which are suppose to mine at 50 gh/s. But cost $2,499.
Those who made the most money out of a gold rush were those who sold tools to miners
Well, not the most, but certainly the most consistent. But I don't really think you can compare mining gold and bitcoins(well, I mean, if you
really want to ), the risk is there, but quite different.
