If Bitcoinica does part-payback but not 100% payback, does the part-payback go to the lender or to you?
to the lender of course. Anything i get from bitcoinica, related to my claim, will go to the lender.

Would they get the partial payback and the 18.75?
yes but, only up to 40 btc

example 1:
in december i payback 18.75 btc.
in januar i gets paybacked my 40 btc
i then payback 40-18.75 btc = 21.25btc.

example 2:
in december i payback 18.75 btc.
in januar i gets paybacked a part of my 40 btc, 20 btc
i then payback 20 btc, and have a rest debt of 1.25btc, in case bitcoinica pays me back the other 20btc(or just 1,25btc)


in any case i will maximally only payback 40 btc, but 75% of the loan will be payed back.

new terms:
25 btc loan.
75% garenteed payback by christmas(18,75 btc).
full 40 btc repayment when/if bitcoinica pays me back.


the math are:
chance*(debt-loan)+(1-chance)*(-loan+payback*loan)

so on a 30% chance that bitcoinica will payback, lender wins.

Fair?
if by "payback" you mean "guaranteed fraction" then the math is correct. However I'm not sure I'd agree that the lender wins. Christmas is a long time away, and you have to take the time value of money into account. Here in the BTC Wild Wild West, 1% weekly is very common. This significantly devalues the "Christmas" part.
its not a 15btc back guarantee, its a 50% back guarantee.

yes but the 50% back doubles that, so 32btc, if you thrust me 100% that im keeping my word.

You got your math wrong Smiley If there is a 40% chance that the 40 BTC are sent back, and a 60% chance that they are not (meaning the lender will receive only 15 BTC), then the expected value is 40*0.4+15*0.6=25. So it would be a bad operation to give you 30 BTC for this.

If P is the probability of Bitcoinica money being paid back (between 0, default, and 1, certainty), then people should buy this option for no more than 80*P/(P+1). So, if lenders think that there is a 40% chance that Bitcoinica pays back, they should not pay more than 22.85714286 BTC in any case. And even that would mean a 0% loan for many months in the "mean" case.

With a 10% chance of payback, the maximum that a lender should lend is 7,27272727 BTC.
We came to the same conclusions, just phrased differently (e.g. I said "lose 5" you said "EV of 25"), except for that last bit. The maximum the lender should lend is 17.5 BTC. You forgot the 15 BTC guarantee.
.1 * 40 + .9 * 15 = 17.5
Obviously, the lender is also losing time value and is the one running the risks. The factor of most importance, in any case, is how much the lender trusts kokjo and Bitcoinica to keep their words.
its not a 15btc back guarantee, its a 50% back guarantee. i understand the math now.
