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?
I doubt if anyone gets addicted to investment, because if one tries to get such an addiction, they may still sell off their asset (Bitcoin) just to keep up with their needs when it becomes too pressing on them. If anyone does that, there's always a disadvantage that follows. For example, someone bought Bitcoin worth $800 when the price was at $29k, and after one week, a need for $300 arises on his side. By then, the price of Bitcoin had dropped to $27k, and because he really needed the money, he just had to sell at a loss. Even if the investment is in other things from which they can't just withdraw their money at any time, they end up borrowing from others to solve their problems.
It's true that some people are so self-determined to save up and invest, but I have not seen someone who is so determined to the extent that they refuse to buy food and eat healthy, but rather they only limit their lavish spending and also manage what they have, like the clothes you mentioned. If they still have some good clothes to wear, they don't bother buying new ones when they see one, but that doesn't mean they wear rags.
@OP, if it's in the way you meant it, I haven't seen any case where someone gets so addicted to investment, just like gambling, that they end up not spending on other important things.
