if i were you,( and i am in most ways as a small miner) i would look at my BTC stach, purchase some U2s from a group buy and double or trible my hashrate, and put my BE on ebay for $15 bucks, then use that mney to buy a few more U2s off ebay, wind up with several times more hash with no more fiat expenature and no more mining infrastrucure cost. and with the hash you add from the ebay purchase you should return your BTC invest, maybe not your ebay purchase also but at this point we are all throwing money down the drain hoping for BTC exchange spike!!
