GPU miners can't mine it fairly, it's impossible, arguments there in wiki ain't make GPU owners to mine it. Lots of Titans will land on this coin and in a week expect incredible difficulty. You have to make it at least scrypt-n, so home miners can win several months. This is it. Good luck.
It's not easy these days to come up with a system that covers all the bases. On one hand you have botnets and AWS instances dominating networks and on the other hand you can make it difficult for regular GPU miners such as yourself to mine fairly.
At least we're still at the point where someone with a decent GPU setup can still accumulate a decent amount of Bitmarks still. I know I've rented a few GPU rigs over the last week or so and they were good value for the money.
A few MH still goes a long way at this point.
