According to my calculations, for me anyway, each K16 cost $328.29.
Even at $1k a BTC, I am pretty far from ROI, on this deal.
But, it's getting closer every day....and...I'm securing the network, which I'm sure is looking incredibly attractive to attack right now.
I got $306.75 with even shipping included, I've figured its better to mine with them until there is barely any profit then sell them to ensure ROI
