I think the block rewarder needs to reflect the cost of PMC on the exchanges.

Now, there's two ways of doing it;

1: Block Rewards go up as exchange prices go up

2: Block Rewards go go down as exchange prices go up

Option 2 might seem more intuitive, but if you think about it, it's not actually the best option. When prices go up more people will be mining PMC, and because the harder you mine PMC, the relatively less you receive, you actually want the rewards going up, so rewards remain stable as difficulty increases. I will look at a way of incorporating the current PMC price in the script, which would make the block rewards variable by price. This would be a stable approach.

This is also an incentive for prices to increase.

When you think about it, mining PMC is a bit like mining on a pool in some ways. The more hashpower you throw at it, the more proportional your share is of the txfees. It's mainly a disadvantage to smaller miners, who would benefit from mining on a pool.

I really like the idea of a pool that will mine the most profitable altcoin and then sell it for PMC on the exchange automatically. This would be such a big deal for Premine, and I will personally spend my own PMC in paying for such a service.
