Thanks for your reference, we answer some of the questions here
There are no 2TH machines, None of them have shipped yet!
All of our 2TH/s ASIC Bitcoin miner Hardwares have been manufactured in our private lab so we did not have to wait for unreliable pre-orders to be delivered.
Just doing a quick google map search on the location advertised on their site brings up a building that is under construction and located in a port.
We searched our address on google map but we could not find the mentioned under construction building we are located in!
Why they only accept Bitcoins
Our system totally is based on bitcoins and we have to withdraw with bitcoins so it's not so odd to accept the only currency our platform have built on, but we are planning to add other payment options in the future
if they have that much profit possibility why would they not mine for themselves?
Bitcoin mining difficulty is going up promptly and the profit we can make today wont happen after a few month so we need to expand our mining infrastructure too fast Thus we use our revenue from renting part of our available hashing power to raise our hashing power and to expand our mining farm on a daily basis, therefore our urgent plan is to expand our mining farm and we earn profits from adding more hashing power to our infrastructure not only by doing ordinary bitcoin mining.
I appreciate you taking the time to answer questions, but you haven't really provided any solid information.
We know little to nothing of your business operation; where are you located? Can you take some pics of your office, the machines, perhaps divulge some information on you and your business partners. You have machines that we're not privy to, meaning that without pictures or proof of their existence they can be just figments of your imagination.
I'd hate to accuse you of scamming when you're trying to run a legit business, but there is way too much information left out (at least for me).
