Speak for yourself.
Dogecoin profitability is "only" 0.03+ MH/s.
0.03 per MH/s show me your calc please. Whenever I do calc middlecoin is similar to dogecoin solo. Doge although has lower fees so still should be slightly better however depending how high you can sell and if you watch the market (which not everybody has time for).
I've switch 1 of my rigs to dogehouse, per 24h I got "only" 0.019 while on middle 0.021 however I guess it was due to the right time of sell. Still I can't see those 0.03.
