I have 1 more Ant on order and that will fill my small hub, just going to let em run in the corner! once i have enough BTC i will then spend that on a bigger hub, and keep putting my BTC in more miners, hopfully growing my empire!..lol
So what have i done is made my initial investment, and now said to myself it either live or dies by its own mining potential. will see what happens over the next year if i make enough btc to keep expanding, hopfully keeping up/ahead of difficulty growth and slowly increase payout frequency.
Wait and see now.

Oh and cooling simply extends unit life! it may help with reliability as well.
If Anyone is interested i do have 3 BE's on ebay at the moment! just in a straight auction.
