This sits in "Securities" rather than my usual lending section thread because it is a little more aggressive in approach and not as reliable.

Based on some work I have been doing I believe there is space for this particular fund and because it is a little different labelling it Kraken seems appropriate.

Basic parameters:

• Fund commences 19 August 2012.  
• Investments may be made in multiples of 100BTC.
• Withdrawals may be made in multiples of 100BTC.
• Contributed capital is backed by my personal funds.
• Returns will be paid weekly (currently planning on Fridays) - no compounding or automatic reinvestment.
• Target and maximum return 2.5% per week. (for the ponzi people, that would be 361% annually, but it's only 130% because it is non compounding.)
• Minimum weekly return 0% - any losses will be funded personally.

You will need to request a unique deposit address and supply a unique return address.  I will have a sensible limit on the number of investors because I don't want to spend my whole life doing weekly payments.
Returns obtained over and above 2.5% are taken as my fee - that's how I can afford to support the minimum return and "insure" the capital.  If I have coins sitting idle, they don't lose money, but impact on the average return.

Obviously the question is "What am I doing with the coins?"  
If I was to provide a simple answer like buying 50 BFL singles and going mining, or putting 10,000 coins into XYZ asset on GLBSE then there wouldn't be much science in that and it would ruin the market that I am looking at.
Also, I do expect people to assume funds might simply be going into BS&T and accuse me of feeding an illegal activity.  Due to the vitriol that goes with that, this will not be an open thread because there will be no point debating that.

So what am I going to use funds for?  Some will be going into my "vulture" capital business interests, some into some long-term BTC investments I have held in real-life ventures (such as an equipment manufacturer), some in BTC assets, a small amount of futures trading, some into various risk/reward adjusted investments that are available in the bitcoin world.

Edit: Currently 25 registered users.  18 currently paid.
Edit 19Aug: The largest commitment made was 1000 coins, and that was before the closure of one of the largest (and smartest) BTC operations.  In fairness, I consider a 1,000 maximum per account is appropriate making the absolute maximum size of Kraken Fund 25,000.

Two updates:

1st: with 14 registered participants, I'll be limiting this fund to a maximum of 25 and closing it at the end of the month because there is some manual processing that goes with the weekly payments.
2nd: If there is sufficient demand, I will consider a kraken#2, but with a 2% weekly max rather than 2.5%.

For now, the Kraken fund is closed to new accounts.  They were provided on a first come, first served basis.

I have a couple of people that have indicated they are interested in accounts, but I want this to get up and running first.  Depending on interest, there will probably be a Kraken#2 in September.

Might be one of the higher yielding.  Expected payouts between 0% and 2.5% per week.

Edit: Due to a short-term window of opportunity I have secured the first 100 BTC of profit using some of my own coins until the remaining funds are deposited.

Yes, but I think a second Kraken fund will be more likely.  Let me iron the bugs out of this one over the next couple of weeks and set up a few other bits and pieces.

You are welcome.  Technically I don't have to do any more work on this until September as I have locked in three weeks of profits already. 

13 of 25 initial payments have also been received - thank you 

I'm interested as well.  Hit me up if a spot opens

I would like to preemptively register my interest in Kraken #2, assuming Kraken #2 is of similar nature to Kraken #1.

Also interested for #2

I am interested in #2 too.
