Addiction is a word that most persons have made look like is only used for bad things whereas it is not true. Someone can be addicted to something meant to be good that it becomes bad. Trading is good, but there are people that are showing similar signs that addicts to other dangerous habits still show.
There are traders who are addicted, they have ignored other people and activities so much just trying to focus on trading. That is not very good and an obvious sign of addiction.
