Don't know why they picked me...
List of alts to mine...
It was the hat dude... the hat... ;P
Here is what I use for a good list to mine.
http://www.coinchoose.com/http://www.coinwarz.com/As for the other guys comment about "ROI", that is "Operating ROI", not "Initial investment". If there is an "Operating ROI", then your "Initial investment" will eventually be returned. You can't use "calculators" that speculate horribly, and don't take into account "when you cash-in".
If you only mine 1 BTC, ever, and that value turns into $6,000/BTC, in the life-time of the unit. It has made a ROI, as long as you have not spent $6,000 in electricity. (That is operating ROI.)
You can't "Claim" it does not offer ROI, if you don't have it, and have not operated it. Also, you should never use BTC as your "source of value" to MINE. That is NOT the best coin to mine. It is the best coin to cash-out. But I digress. 60GHs units are not dead, and will last for years still. Just not on BTC directly. 80GHs, even longer.
It doesn't matter what the value is while you are mining, it matters what the value is when you cash-out, what you mined. Thus, always mine the lowest diff coin, no matter what the value. Value will follow, because your mining will reduce the coins they get. Thus, they will offer more. That is why alt-coins live and thrive. Never waste time mining a high value coin that is also a high-diff coin. It will only be less after you start mining it, and raise the diff. (Because high valued coins go down, unless you have the majority of the hashing power. Which none of us will ever have, except possibly on a new coin or a low-diff coin.)
