I am not happy about it either. If I am not mistaken the old sha 256 price for 10GH was $1.20. It went up to $2.40, basically doubled the price. Seemed fishy when the return was about 4x, but seemed silly not to throw a few dollars there to see what happens.
I don't think it is a matter of the company seeing too much in sales and a backlog, I am worried about the solvency of the company.
