Each GUI miner has a very large commission. This negates all their virtues.
Agreed. I have never used GUI miner. Why pay 3%-5%-8%? Other applications have 0-1%. And CLI is better and work faster.
As I already wrote in the title, this thread is only intended to help Newbies to gain their first mining experience.
Well I once tried minergate mining on my mobile device sometime 2017 and in my opinion it was horrible.. Although the spec of the device I used then was not too good but based on the difficulty rate of this cryptocurrencies back then I expected lot more performance.. Well I ended up getting discouraged and eventually stopped mining..
Well, you don't use a portable device for mining.

People please remain a bit realistic.
