I have a not-so-good miner in terms of mining, like with CPU mining with LTC, it goes to 15 kHash/s which is pretty low.
I thought nor pool mining nor solo mining will earn me much when at this speed. But what if when mining other crypto-currencies like NVC, TRC or PPC? They have a lower difficulty level and probably would yield more in solo mining.
Simple question is that, if I want to mine them, what should I do, solo or pooled? and Why?
Also, how much time approximately will it take to mine one block of any of these at this speed?
