Be careful buying into this, this screams scam!KNC does refunds, so there is nothing stopping the OP from just canceling his order once he sells fake shares. The OP has no trust whatsoever and claims to have just spent $20k on mining hardware. The prices are also outrageous and prove that he is at least trying to be shady:
250 MH/S divided by 500 kh/s = 500 shares.
$10000 (the price of 1 Titan) / 500 = $20 or about 0.044 BTC
The OP is asking 0.17 BTC or about $76. Almost 4 times the actual cost.
Even the so called "deal" of 3 MH/S for 0.9 BTC is way overpriced.
250 mhs / 3 mhs = 83 Shares.
$10000/ 83 = $120 or about 0.267 BTC.
Again the OP is asking for almost 4 times the actual cost, not really a "deal".
The OP also contradicts himself in the post. He says in a few places that 250 MH/s is available and in others that 500 MH/s is available. If he proofreads like he manages this group buy, you are in trouble.
This is just speculation but the tone of the post is also very similar to the user minewithmind who scammed tons of people over in the group buy section. Minewithmind was also Italian, used the exact same style of punctuation and random text coloring. He also supplied the exact same style of picture for evidence.
The OP should have signed up for a preorder and paid, then given control of the account over to someone trustable like SebastianJu. SebastianJu then changes the password so that the OP can't cancel the order. SebastianJu also then opens up an escrow account for group buyers. This is what was done in Anykeywhy's very successful Titan group buy that just closed here:
https://bitcointalk.org/index.php?topic=522707.0Also look at the price differences. It is clear that the OP here is trying to scam.
Basically don't do this group buy unless the OP comes through with actual proof beyond an easily photoshoppable picture.
