Personally I LOVE to see the hashrate decline to sub 100MH/s. Most of the miners that quit weren't in it for the long haul and the ones left are saving their goldcoins.
Forget the miners. That's only a problem when a coin is first started. It will never be a problem for GoldCoin. I think we need some type of utility. Any type of utility. In all truth though, GoldCoin is doing quite well. No one can argue that the long term trend is way, way up.
