If you have a look at the portfolio below the OP you can see that the weekly incoming dividend is 7.2 btc. 4.5 out of it from Obsi. If it goes to zero the remaining will be 2.7. Divide it with the number of outstanding bonds and you will get. 0.016 btc per bond weekly. If 0.01 goes into dividends 0.006 left to get the NAV growing slowly.
This calculation does not takes into account my fee which I will not take the first eight weeks anyway.
The NAV would go to 0.6 which would be a big loss that's right. That's why is called High Risk. But I am not agree at all it is a ponzi. It would be if I would use the money from investors to pay out dividend. But every single coin went to GLBSE assets and I paying the dividends from the income coming from them. I can not deny OBSI is ponzi, it might be. But my operation based on it at 40% and continuously decreasing.
The parallel with the mortgage is very misleading. A single house is not generating income V.HRL does. If a house burns down it become useless but if V.HRL loose 40% of its value it still valued at 0.6 so the investment did not go to zero, and still able to pay dividend at 0.01 BTC per bond. The current value of bonds paying 0.01 weekly are close to 1 BTC on GLBSE even if people does not now anything about their backings.
It is more like if you have mortgage on 10 house and 4 burns down you would be able to pay the dividends on the remaining 6. It is sad that those houses were burnt down where the best tenants used to live. But the rest of the tenants are paying well too average 1.6 percent of the value of your newly built properties.
In real life for a house which worth 100.000 dollar you cant get 1600 rent weekly. But for properties on GLBSE you can. That's a big difference. Although at a cost of high risk.
So the question is when OBSI will default. If it does right after you bought this bond then it is bad but you "only" lost 40 percent of your invested money so you still better off then if you would put it straight to OBSI. And you got the 0.01 afterwards weekly. But if it will does after two months, when it will be less then 30% in my portfolio, your loss is significantly less. Nearly zero, because you took 0.27 BTC per bond as dividend by then.
That is the risk what involved here.
If I have a strong demand from investors to drop OBSI in short amount of time, let say within couple of weeks to 20 percent I will do that. What comes with it I will have to drop the weekly dividend to 2 percent. If investors prefer less risk with less income I am okey to go that direction. I am willing to drop down it to 20 percent anyway but in few month not in few weeks. If it happens that way there would be no reason to lower the dividend.
