Well the chances of that are slim. If you had started mining PTS at it's release and sold as soon as the first buyer showed up, you would have profited a lot.
The guides are mostly coin specific and can be found in this sub forum.
Alright will scour around, but do you know any that might be possible to make a profit from?
The current CPU coins that are best are XPM and PTS.
You could try mining them for a profit. Although I'd suggest keeping track of new releases and jumping onto an CPU coin as soon as it gets released.
