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.
I'm never really sure you'll find one of those, even if it does, then I think the 1 in 1000 chance is still too low to be said to be the number of occurrences. It makes no sense to get someone to invest aggressively like that, it's too extreme to do even if they are confident about the potential return over a certain time frame.
In fact, meeting the needs for clothing, food and shelter is necessary instead of prioritizing investment plans and interests. The most valuable health instead of the value of the investment. The stomach needs food to supply nutrients throughout the body, the brain needs refreshing and the body needs a comfortable place to live so that all of that becomes a priority.
