As on the website
This means that the 280 BTC you list as a payout is clearly false, if you are giving back up to 0.24 BTC of the original 'investment'.
Total payout should be (what you send out - what you took in), not just what you send out.

Also, pictures of rigs?  The screenshot of what you have on your website is just from a web calculator, not a BTC interface saying hash rates.

6 BTC a day is around 120 GHash, or 240 good GPUs.  Even at $300 a pop, that's $72k on GPUs alone.  Any chance we can get images of the setup where you are hosting?

The site is updated once a day.  Though it's been >24 hr and mine aren't up there.  But the list of 'what we have payed out' was updated yesterday, over 25 BTC in a day.  That's a equivalent to 500 GH/s or 1000x 7970 GPUs before they take a cut.

In the My Mining page, there is a new link:

"Next Server Update (Click Here)
Payouts are made around the clock. The server updates information below in blocks to prevent broken links."

Which tells you when the information should be updated.

As long as you stay active at bitcointalk, people will grow to trust your system.
I would suggest a page of images of your rented rigs, as well as in-progress images of ones that you are building.  If you can prove you have the HW for such a scheme, again people will go to trust.

I'm still wary regarding the 2600 MH required for a 0.25 BTC package to pay off.  I'm not wrong in the math, that's 4x 7970s for 3 days to earn that back before you even take a cut for yourself.  Unless you have 20-50 initial systems, each with four cards, or hands on a few Avalon/BFL rigs/shedload of FPGAs, you are going to hit limits very quickly.  Those that make it within the limit of course will extol the virtues of the system as you continue to grow.

This is a very legitimate way of looking at the scheme.  Rent out your HW, renter gets 90% of perf, 5% goes on expenses, you keep 5%.  Over time you can buy more hardware, and it builds.  Keep a pool of BTC to pay out in the event of an outage.

Though after a few hours of thinking about it today, there are a few issues.

- It offers a way for your BTC to earn money while idle.  If I have BTC idle and I can get a return on them sitting idle, then hell yeah.  Alongside normal mining, this would be a great system.
- There are no images of the mining rigs, no up to date reasoning of why XYZ.  If you follow the bitcoin addresses, lots of 0.25 go in, and some 0.337 go out.  If the owner is hoping that more people get interested, then he can pay some of them out.  This is eerily similar to a Ponzi scheme if no real evidence is being had that they have miners.  Take, for example:

The 0.25 BTC option.  You get ~0.3263 BTC back.  Now in order to earn 0.3263 back in 60 hours (premium users), at current difficulty, you essentially need 2630 MHash/s just to break even.  So when you send those 0.25 BTC, you should be 'renting' approx 4x 7970s for 60 hours.

Clearly the owner hasn't thought this through - almost 1000 different 'packages' have been bought on the site (which hasn't updated in 6 hours) that are in the pipeline.  Apparently they're installing 3 new systems tomorrow - if that is another 12 7970s, then they have enough power to accomodate 9 requests for 0.25 BTC every three days.  So of course, this makes me think 'Ponzi', unless the owner has actually been taken unawares by the demand, or they are using the machines to mine other coin and transfer over if it offers a better return.

If someone is making money through work, and they have an opportunity for the money they have earned grow without doing anything themselves, then they'll do it (assuming no risk).  That's why people have high interest savings accounts.  The bigger the % payback, more often than not the bigger the risk (hedge funds).

Now if the owner had a 1500 GH/s system from BFL, then it would make sense.  He could create ~75 BTC a week.  But doing some math, if I started with 1 BTC and reinvested all I got back, in a month in this scheme I would get back 15.18 BTC if I kept 5% each round.  Any scheme that could 15x my money in a month sounds too good to be true.

However, it is up to individuals to make a decision either way.  Clearly people have had returns, although there is starting to be a backlog and the site doesn't autoupdate.

So only invest what you can afford to lose! 

Pretty much this is how it would come to pass.  You buy a house, but rent out 80% of it to pay the mortgage and get a little extra (if you can convince people it's worth it).  Over time the house is paid for, you have equity, and you could reinvest.

These people could, over time, build more rigs as they build equity.  Those that 'invest'  get a 9% return, and when no-one is invested, they mine coins for themselves. They're dealing with all the hardware issues, any downtime, and will have a pool in case of severe downtime to pay off those who have invested at a small loss to the website.   

It's a pretty smart idea.  Obviously only invest in as much as you can afford to lose, just in case.

Personally I felt that slush's pool wasn't that good unless I could keep a card on 24/7.  When I was BTC Mining I decided to move to BTCGuild due to the PPS system and get a more regular return there.  Slush's pool, while good and I was there for a while, was just too variable for me.
