Also...
HashFast/xCrowd are offering a "Miner protection plan" of some sort. (If difficulty goes up so high that you can't ROI, they will provide extra chips for free... something along those lines.)
I'm a bit weary to order from a company that doesn't also provide this, because if they delay then you're out of luck.
I feel like a "Miner Protection Plan" is needed for any new start ups to be taken seriously.
Hashfast offer raw chips, but you have to pay for associated parts, assembly and shipping. Plus you'd presumably have to wait for such additionally hashing power to be made for you. This all negates any miner protection. Furthermore they guarantee refunds out of what, the pool of monies they have spent on development and wages? No third party assuming liability, no real protection.
X-Crowd offer protection on a global network of sub 350million in difficulty. By the time they deliver it will be beyond 350 million in difficulty, therefore such protection is also negated.
It's just marketing. You either fall for it, or you don't.
Cointerra looked promising as they promised to accept a secured payment with potential third party assuming liability to really protect their customers funds, but at this pricepoint there is no way they could have even genuinely considered Paypal as a payment choice.
I understand that the extra hashing power is only provided in chips (not assembled), but it is better than the NOTHING you would get from the other manufacturers if they are delayed and you won't make ROI, is it not?
Obviously xCrowd's miner protection plan of difficulty <350 million is not really a miner protection plan. I did not know they had placed such a limit on the difficulty. HOWEVER, they also are offering escrow so I fail to see how a gap in their miner protection plan is really that big of a deal. HashFast's miner protection plan seems decent.
In one case you are just screwed if they delay (KNC), and in the other case you can pay a little more to get the chips assembled and still make ROI (HashFast). I fail to see how not offering a miner protection plan is better than offering one...
Try looking at the situation without your KNC is the only legit answer goggles on...
