Gigamining is growing - great, it must mean something good, we are all happy!
So maybe now you could turn 5Mhash/share into at least 6Mhash/share?
You must be either illiterate or incredibly naive.
The GIGAMINING
bond is a
debt instrument with a
buyback clause and not an equity interest. As gigavps's operation grows it increases the network hash rate which increases difficulty and decreases the bond coupon thus reducing his debt burden. Everything else being equal the larger gigavps's operation grows the less GIGAMINING bonds are worth per unit. Therefore, it is in gigavps's financial interest to make the GIGAMINING bonds yield the least amount of bitcoins, consequently be worth the least amount possible so that he can then retire the debt instrument through exercising the buyback clause and still perform according to the terms of the bond contract exactly and honestly.
I think you have confused some terminology or are completely missing the point, how bond, its price, coupon and yield are related.
His coupon is "a number of bitcoins equivalent to 100% PPS output of 5 MH/s,"
If difficulty goes up, he will earn less and so will all the bond holders. His debt to mined BTC remains proportionally the same. Will the bond price drop and yield (not coupon!) go up? Who know, because this happens to all the bonds out there.
If his mining operation grows and number of bonds outstanding remain the same, it gets easier for him to pay the promised 100% PPS output of 5 MH/s. Lets not forget, that he will have a bigger reserve to service the debt, hence mined BTC and outstanding debt (bonds and coupon payments) ratio drops. In normal world, this is good news.
Bond are safer now and the price of the bond goes up. If bond price go up, the yield drops but the coupon (100% PPS output of 5 MH/s) stays the same. Do not confuse the yield and "coupon". Price sets the yield to the buyer of the bond.
Now, if his mining operation grows and number of bonds outstanding also grows proportionally, nothing bad really happens and he can keep paying 100% PPS output of 5 MH/s.
If he gets greedy and issues new bonds but mining speed is not increased proportionally to service the additional debt, he can have a problem paying out 100% PPS output of 5 MH/s. In the normal world, the bond price will drop because of the risk, hence the yield will go up to reward the risk of the "coupon" - promise to pay 100% PPS output of 5 MH/s.
