This discussion is not about gambling, it is about investing, but I will use gamblers to make an example.
Using gamblers as an example who start out with just the intention to have fun maybe and then along the line turn into addicted gamblers that gambling begin to affect other areas of their life like their wellbeing like they stop spending on some important things just so they can make money available for gambling. Now talking about investing, I think it is possible to become addicted to investing so much that it begins to affect your wellbeing, like the person stops spending on other important things like good food, good clothes etc. just so they can have more money to invest? Do you consider that kind of addiction dangerous and not good?
Investing addiction could be possible, there are people who neglect their basic needs and other financial needs in order to invest more money to their chosen investment. And i think this kind of addiction is dangerous if it leads to a person neglecting their basic needs, such as good food, clothing and other important expenses. Neglecting these needs can have a negative impact on a person's physical and mental health. However, investing can also be a positive thing when done in moderation and with careful consideration of ones financial situation and priorities. It is important to maintain a balance and not let investing consume ones life to the detriment of other important expenses.
