amazing

Hi guys,
this is my first post on bitcointalk, so please bare with me and my English.

The following are my speculations,

1. The farm is mining at 340Th/s but where are the stats for block finding, user shares which is a basic requirement for running a cloud mining or even for a pool.
2. The company doesn't have a registered office?
3. User security is taken for granted, no two factor authentication, it entirely relies on cookies to identify users and pretty basic security for a cloud company.
4. The value of hardware, even if you today buy cointerra's 1.6Ghz miner at a discounted price of $3499 (excluding shipping) which gives us $2.18 per Gh/s and considering pbmining ($430/BTC today's value ) gives us $2.279 per Gh/s.
Are they going to generate enough revenue for running 340Th/s farm for a constantly 5 years or even for upgrading hardware???
I don't see any profit is made by the company.

I have just brought 5Gh/s contract to validate all the info, on wards I wont put any money here.

My best guess is they are collecting money from paying users and repaying them in small fractions so many people can trust and join and they will generate heap of money and then boom...
