I came to Heavycoin because it was CPU only. Even built a mini cpu farm just for it. Staying... because well i am. Moved my GPU's to it also. New cgminer version giving about a 38% increase in hash for me, very nice. HeavyCoin needs to expand the network of merchants retailers, marketing ect if it's going to go anywhere. ECCoin has an extensive marketing campaign going right now, would be nice to see HeavyCoin move in that direction.
There's currently a marketing effort underway, but if the community wants to launch further (and larger) efforts, then the Heavycoin devs will back such community efforts using the Heavycoin Fund.
