Im relatively new to mining but find it hard to get information on dual/merged mining. can you guys shed some light on it for me ? Is it even the same thing ? Can I dual mine any coins on the same card at the same time or just coins that run on the same algorythm ? Is 2 the maximum of coins that can be mined at the same time by a single card ? I read a pretty old announcement that DMD and GRS can be dual mined because they both run on groestl for example but I wouldnt know where . Thanks for your help
