OK adding a coin, but how is profitable to mine DSR

?
And i want to tell all that unimining.net had some saturation on neoscrypt pools. I tried to mine GBX at this pool and they can't provide me any blocks to mine.
in additions :
1/ I'm not sure that all of us have a folder named KTccminer-817 in /home/m1
2/ I think there is a "typing error" in the command line
-o stratum+tcp://$DSR_POOL:$DRS_PORT
must be
-o stratum+tcp://$DSR_POOL:$DSR_PORT
You have to be more precise an readable in your post. You can post a modification understandable and easy to do without being a computer scientist or a computer technician. This system is named "easy to use" for reminder.
Thanks for adding.
You 're right sorry for the typo,
A patch is the easiest way to do the modification, you don't even need to know where to put the lines in the patched file.
just do
patch -p0 < file_with_the_patch
fastest than anything
KTccminer 817 was posted few days ago here by Papampi
I don't know if this coin is profitable, I just want to mine some so made the modification and shared.
