Guys thanks for the reply. Let me put it this way. If you want to buy 4860 ghs in the market (0.00092/3/4 x 4860) you will need Aprox 4.5 BTC. Then again, yesterday S7 miners were sold at 5,4 BTC. (Aprox 0.0011 per GHs) and also the waiting time. Am I missing something here? Who on earth buys an S7 miner at 5,4 BTC while you have much cheaper Ghs available to hash right away...still confusing.
