I agree with dree12.
Can anyone explain how merged mining would NOT drop the price down to 0?
The price won't drop to 0 if the coins are useful
So yes you're right, the proce will drop to 0
Bitcoin are also not "useful". If we added 10M bitcoin to the economy today, price WILL drop to zero.
Do you understand the concept of "50 coins per block"? Why are you talking about adding 10M coins??
Merged mining = rapid increase of coins mined until price decreases to near-worthless. This is because to maximize profit, the entire bitcoin network will mine solidcoin until the difficulty reaches 0.3x bitcoin difficulty, when it will balence itself out. This is nowhere near close to happening, and solidcoin will slow down the difficulty increase, which means that you will add in effect more than the size of the current economy.
