If they are not asking for upfront payment, it won't hurt to try.

well im just about sing in will it be a mistake?

I guess the best advice I can give is just to be careful where you put your money and think twice, even three times if it helps. It's difficult to say, if I was you I would not invest.

i just signed up, link in my sig too.... but they certainly do have quite a well developed website.. it is russian so who knows.  one bit advise is make sure u dont give any serious details like a regular password, i have also noted they want phone numbers etc but not necessary on sign up.

0.00130800 BTC was my profit for today (200khs from free promo). You get that for 10 days. Not worth it for now (they have to show they can be trusted).

I also signed up for the site but it seems a bit risky to me at this point. I recently got an email from them saying that they were having a sale on the Khs and you could use a promo code to get 10% off...but you still have to spend at least 0.02 BTC so I am not convinced it is worth spending for. This could just be a way to get people to spend money sooner and then the site will disappear :/

On a related note, most of the things I have read about cloud mining are that it is not profitable for the person buying/renting the Khs/Ghs. I haven't really looked into it that much (as far as doing my own calculations and whatnot) but I am not convinced that it is worth spending money on currently.

I'm testing several cloud miners with small investment in each one

Pros:
Very cheap and good profit currently at 0.00006680 Mhs
You could sell your Mhs and go aout at any time

Cons:
There are others with more profit/Mhs relation
Some people understand they are not trustable, I've tried myself some withdrawals whithout problems (Could provide the evidence if required)
They mine altcoins and change thm into BTC for paying, some people understand that this could damage BTC in the long term

Pros:
they give you 200 Mhz for "free" testing (In order to retire or use the profit of those 200 you need to buy them real Mhz)
Very cheap and good profit


Cons:
There are others with more profit/Mhs relation
You couldn't sell your Mhs and go out at any time, contracts are for 2 years
They mine altcoins and change thm into BTC for paying, some people understand that this could damage BTC in the long term
Some people understand they are not trustable, I've tried myself some withdrawals whithout problems (Could provide the evidence if required)

Pros:
Trustable site with long history
Market included, you could speculate with the coins and the Ghz you have and obtain additional profit from that
You mine other altcoins at the same time

Cons:
Very expensive, really you loose money if only mine

Information for other sites will be added soon.

I also don't understand, for me the key concept is digital and decentralized currency no mater which code use.

But here is one of several articles related to that if you have interest to read

http://themisescircle.org/blog/2013/08/22/the-problem-with-altcoins/

Hashprofit and tradefocus looks the same to me hyip investments that's all. I say stay away from them.
Invest in some other more popular and know cloud mining website.

I just signed up to at least try their free 200 Kh/7 days +a 0.0001 BTC bonus. IMHO, their site doesn't SEEM to 'scam-y', but who knows. I think the amount of free BTC that they're giving away is feasible; if they can create better mining hardware than I can with my money and advertise a lower Kh/s/$ than they can truly make, they profit too, though I have little knowledge of mining whatsoever.

Nonetheless, I forget exactly when I signed up honestly, but their interface says I have 5 days left and my balance is currently 0.00295622. I'll come back to the thread at the end of the trial period, do some calculations, and figure out how long it would take me to get back a minimum investment (0.02)... I'm considering it, but without all the data, I'm definitely not doing something that'll take more than a reasonable period of time to profit on (given the possibility of being scammed as well).

If you wanna try it, I'll shamelessly post my ref-link to their registration page, and even link this line to it:
