Investment can be never considered as addiction as investment requires you to be financially stable to that extent so that you can use your extra money in any profitable venture and in today's time where poverty is increasing with everyday increasing inflation people are having hard time in meeting both ends meet .
They can hardly manage their monthly expenses within their pays so investment is for rich only .
I think it's more about what you do about investment. Like for example, I could invest my money into just bitcoin and hold it for many years and check the price maybe once or twice a month, that would be an investment that is not addictive. Or you could invest and check the price every 5 minutes to see how it is doing, that would be considered addiction.
So, it's not about the investment itself but HOW you invest, if you invest like an addicted person and constantly try to do something about then it is going to be a trouble. Many people who are new start like that, and should not be considering that situation as normal. I feel like the best thing to do in this case is to invest and let your investment be until it reaches low or high enough for you to stop.
