Hey newbie, welcome to this educational, knowledge-giving, and time worth-spending platform. Addiction in my own words simply mean, the uncontrollable engagement in an activity to the extent that it affects your daily functioning as a human being and as a member of your community at large. From what you have described, it doesn't meet the yardstick to qualify as an addiction.

As a newbie on this forum, if your goal is to increase your knowledge about bitcoin, that is everything associated with it, then, you will want to spend time browsing and reading through the several boards on the forum. Because, the way I see it there is a positive correlation between time spent logged in and the increase in knowledge.

The only time when I think it becomes an addiction and you have to slow down is when you log in only to search for bounties, making low quality posts, and or merit phishing. Aside these, I think you gat nothing to worry about.
