A quick calculation:
10 Gridseed Kit, 3 MHs = $200 x 10 = $2000
3 MHs at auto switching pool get you, let's see, 0.0045 BTC per MHs, so 0.0135 BTC a day, so you are making $5.805 (at $420/BTC) a day. It will take the buyer about 344 days to break even.
I feel so sorry for those who got snookered.
With gridseed blade it would be 1 blade, 5.8MHs= $1600
.0045 = .0261 BTC/day * $450(current BTC price) = $11.745/day = 136 days ROI
Not bad considering what it used to be
but once Titan is released it is game over.Titan will be produced as Neptune in small qts and not all miners will afford to buy one.
So will be room for all type of scrypt ASICS.
A single titan produces more mh/s than the net hash of many of the smaller scrypt coins. Even if just a few were released it would change the game.
This.
Basically it will be inevitable that script mining will go the way of sha256...meaning you have will have no choice but to get Asics to mine once they come into the game, so the point of getting gridseeds is, you need to.
