Slow down usagi. This is a math thread, not a heated argument thread.
Edit: it's quite possible that I mistook your tone, or vice-versa

Interesting idea, but your analysis is wrong. For one, you don't take into account that no one is going to keep bitcoins in cold storage not gaining interest anywhere. Secondly, you haven't taken into account the fluctuating price of YARR.

You also seem to be intent on mentioning "CPA defaults" in spite of being repeatedly told that we hold money with other people. We can't take the money and run because **we don't hold the money**. Do you see how that works yet?

No matter how you slice it, even at 1.9 YARR is the best deal out there besides pure pirate. That is the point. We pay out 4.3% at 1.39 and nothing else beats that. You can always come up with a pipe dream where it is cheaper not to pay insurance as long as you assume no one ever defaults. That is why you claim it is better to invest directly into pirate and keep coins on the side. The problem is that doesn't make logical sense; no one will ever do that.

In the end, insurance costs money (a premium) which is paid to the insurance company. This is why you feel it's too expensive; because you have to pay something. I get it. I agree YARR is overpriced at 1.89. When I sell the next tranche of shares it should get knocked back down to 1.40-1.50.
I'm going to be answering the part in bold. The second paragraph merely addresses one of the 5 "additional risks and detractors" and I'm going to concede that point. The third paragraph starts with an incorrect sentence, then moves on to make assumptions about lower than current market prices. It ends with a statement based on the part in bold, which I am going to address. The fourth paragraph does not have much for me to debate. I hope I'm not missing anything.

The second bold sentence is easiest: no, I don't take into account the fluctuating price of YARR, however I do provide general formulas which will work for any price of YARR. I then give one example which uses the "last" price.

Now for the first sentence. Let me quote it again, since I've rambled quite a bit and might have put it above the page scroll.

Here, we have a mis-communication. It actually reflects better on YARR if I don't do that. Here we get into time value.

d. The investor loses the opportunity to invest the Guaranteed Capital elsewhere while invested in YARR. In order to spend it on a WikiSpeed car or invest it in the Dank Bank, one must withdraw it and the Exposed Capital from YARR.
What happens is that the 0.89 is risked. Pirate defaults --> it's gone. The 1 BTC is not risked. It's almost 100% guaranteed. Therefore, the risk of investing in YARR at a price of 1.89 BTC is mathematically equivalent to the risk of investing 0.89 in pirate and 1 BTC in cold storage. From there I say that it is the 0.89 which is generating about 0.0674% interest, while the 1 is staying safe generating 0% interest. An investor will put 0.89 at risk and 1 safely and enjoy 0.06 / week. If, however, the investor puts 0.89 at risk directly with pirate (pretend that this is possible, I'm simply working with the numbers of 1 share although this calculation should be scaled up -- the outcome would not change) and then 1 with PatrickHarnett (now pretend that Patrick is 100% guaranteed; I'd say it's close -- again, the outcome doesn't change much), the investor would enjoy 0.0723 / week. Similarly, if the investor put 8.9 with PayB.tc and 10 with PatrickHarnett, he would get 0.7141 / week.

I hope I have expressed myself clearly enough to show that giving a "time value" to the guaranteed 1 BTC actually decreases YARR's value. In truth, I was planning on getting to the time value calculations in a later post in this thread, but I decided to leave the time value at 0% for simplicity's sake.

Note that the thread was not intended to bash you, YARR, or CPA. I do math. I enjoy it. And this thread is not professional investment advice. Smiley


Edit: oops, I missed your point about fees. The fact is that if you want to invest *right now* or get out *right now* (rather than wait for someone more urgent than you), then you'll pay a fee (is it 0.5%?).
This does not matter in the case of, for example, YARR vs FOO.PPPPT (actually, you'll pay a lower fee in foo because the overall price is lower, but let's ignore that), but it does matter very slightly in the case of YARR vs Bitcoinmax.

Edit2: If I need to make myself more clear, then we can do examples which involve different time values. I also had a graphing tool around here somewhere, and intersections are often more visually clear than algebraic solutions.

Local thread rules:
  • This thread is for discussing math, not accusing pirateat40 of running a ponzi scheme or discussing how likely he is to default.
  • There is only 1 rule.

For an easier to understand example of the following model, see this post on how to get 7.5% weekly with the same risk as a direct pirate deposit.

General

1. An "insured" pirate bond claims to be willing to return part or all of the investor's capital if pirateat40 / Bitcoin Savings and Trust defaults

2. Therefore, if an investor believes the insurer to be honest, the investor's exposure to BS&T is limited to the difference: (Invested_Capital - Guaranteed_Capital)

3. An investor in an insured pirate bond will receive less than 7% weekly (the amount one may receive investing directly with Pirate)

4. Therefore, the return on risk can be expressed as (Weekly_Payment / Exposed_Capital)

5. The insured capital in an insured pirate bond cannot be invested elsewhere by the investor.

6. If the investor did not intend to invest that capital elsewhere, the lost time value of the capital is 0%.

7. However, it is reasonable that the investor might expect 1%/week and a lower risk.

YARR
1. The last traded price of YARR was 1.89 BTC.

2. If BS&T defaults, the investor will receive 1 BTC. This is the Guaranteed Capital.

3. Exposed Capital is .89 BTC

4. Weekly Payment is 0.06 BTC

5. Return on exposed capital is 6.74157% weekly.

6. Therefore, it is better to invest 8.9 BTC in a passthrough such as BitcoinMax and keep 10 BTC in cold storage than to buy 10 shares of YARR. (Provided, of course, you trust PayB.tc as much as usagi.)

7. There are additional risks and detractors associated with YARR, including:
    a. Contract C-4: CPA forces a 1.3 BTC buyback. This can happen at any time without breach of contract, resulting in more than 30% loss in Total Invested Capital.
    b. Contract C-5: A pirate-backed issue changes their terms independently of pirate. YARR then changes their dividend payouts, resulting in a loss of market value.
    c. CPA defaults independently of pirate, resulting in a total loss of capital.
    d. The investor loses the opportunity to invest the Guaranteed Capital elsewhere while invested in YARR. In order to spend it on a WikiSpeed car or invest it in the Dank Bank, one must withdraw it and the Exposed Capital from YARR.
    e. Fees might be paid when investing in or withdrawing from YARR.

Conclusion: I will be investing in YARR at less than 1.7 BTC.

PPT.X
1. These bonds do not pay dividends, but are bought back for 1.28 BTC every 4 weeks.

2. For simplicity, we will assume that the investor bought the bond at the IPO.

3. The Guaranteed Capital is 0.32 BTC

4. Let the IPO price be j. j is always greater than 1 BTC.

5. The Exposed Capital is j - 0.32

6. The Weekly Payment is (1.28 - j) / 4

7. Therefore, the return on exposed capital = ((1.28 - j) / 4)  /  (j - 0.32)

8. Fancily (word?) enough, when we solve


we get j = 1.07.

9. How about equating this to YARR?


1.07610627

Conclusion 1: I will not be investing in PPT.X if it costs me much more than 1.07 BTC
Conclusion 2: If you can buy a share of PPT.X for less than 1.07 BTC, and you don't mind letting that 0.32 sit there not gaining interest, then you're getting a better return than investing directly with pirate at his highest rates
and the same risk.
Conclusion 3: Buying PPT.X at IPO for less than 1.07611 BTC is better than buying a share of YARR at 1.89 BTC

Gamma Insured Pirate Pass-Through
This one works like YARR.
Time value of 0%, return on risk 7%: bond price 1.357 BTC
Time value of 1%, return on risk 6.9%: bond price 1.217 BTC

There is no market price for this yet.

Hashking's 50% insured Pirate deposits at 3.3% weekly

A) Non-compounding
Quote
This is the only deposit backed by an insurance where you will be able to see the insurance funds sitting in an address in case of default.  As deposits exceed the current insurance allocated I will add more to the insurance address.  I will currently start the fund with 4,000 BTC which will allow for 8,000 BTC worth of Deposits.
Because the funds are sitting there, I will say that the 50% insured part has no time-value. Therefore, we can simply double the 3.3 and get 6.6% weekly.
Conclusion: it's better to invest half of your money in Hashking's 6.75% deposit and put half in cold storage than to put all of it in the 50% insured pirate deposit.
Example:
put 50 BTC in uninsured; you'll get 3.375 BTC weekly and lose 50 BTC if pirate defaults.
put 100 BTC in partially-insured; you'll get 3.3 BTC weekly and lose 50 BTC if pirate defaults.

B) Compounding
Due to perfect compounding, how much a lender invests in this program depends on their time frame and how likely they think pirate is to default. See graphs and details later in this thread.

Goat's proposed bond
Bond face value 1
Bond sold at 1.5-1.6
Bond pays 0.055% weekly
By now, this is getting pretty easy, so here's the numbers sans-fluff:
Time value 0%, return on risk 7% (upper bond price): 1.785714 BTC
Time value 1%, return on risk 6.9% (lower price): 1.652174 BTC

Conclusion: this is also a good deal. Goat has some reputation from issuing other bonds/stocks, such as Tygrr-Bond-B, Tygrr-Bond-P, and Tygrr-Tech.
