Please explain what you mean when you say that the coins produced with the algorithm X11 are unprofitable?
Hope you do not mind the fact that x11 algorithm saves 40-60% more energy at the same time the heat is much less compared to the scrypt! This means that to remove the x11 in this summer period is unthinkable. Conversely, in the winter is more cost effective to use a scrypt algorithm for the simple reason that the heat transferred using heating. As someone suggested above, the solution is to add a scrypt, but do not remove x11. Of course this is my opinion, but I hope more people share it, because it would mean many investors, digging with x11 to withdraw.
Greetings!
