IF you have the hardware and infrastructure in place. It was still MUCH cheaper to mine on CPU. I'm not sure why you don't grasp that.
Not needing to buy a GPU and use an existing CPU.......
vs.
Needing to use a GPU, spending hundreds of dollars just to match pre-GPU block finding ability.
Even if you have rigs already running CUDA GPU's (for now) switching over from a profitable coin just to 'try your luck' costs more $$ also from earning vs mining costs as you're extending your ROI and having to spend $ on electricity, etc...
Either way, it's up to you what you offer coins, I doubt you're getting many offers. LOL.. I just sold a bunch yesterday and the day before for 6x your offers and the people came to me for the coins/accounts. :SHRUG:
I still hold enough to be worth it once it hits an exchange and if it doesn't not to lost any investment at all.
ps. Once the AMD miner is out (Or maybe it already is) I will be switching my rigs to this as will a bunch of smaller farms and then watch the difficulty rise like crazy. I predict at least 4x it is now within a day or two.
