With around 30 DMD/day with your system is still somehow more profitable than mine scrypt or X11 coins. No wonder alot of people are trying to solomine DMD. Less energy and less heat, more profit. Good decision for moving to groestl. Congrat! DMD network will become more stable. I don't think it will explode soon in term of price, but rather stable and grow like DRK. The fun comes when ASIC scrypt is everywhere and GPU miners move to another algo.
