It becomes abnormal if you are addicted to investing to the detriment of your well-being. To everything in life, there is a limit and if care is not taken after this it will lead to abuse. Having investment sense is good because you know you have a better future but it should be at a percentage.
This is why you should only invest with your extra money, and not go all in.
I have a friend who invested a lot with Bitcoin and other project, and when the bear market begins his well being becomes more affected, it started from anxiety, depression and now he’s under therapy.
Investing addiction is good once you know what you are doing, especially you know how to balance your life and your finances. Don’t let your greed to take over your body and your mind, you have to stay composed and of course know how to diversify.
Having an investment plan is good, but I think investment addiction is not good, as hannahB4 said, as long as it affects health and causes troubles in life, it is no longer good. Everything has a limit and is within your control, nothing is good if you put it first and ignore the things around you.
I also invest a lot in bitcoin because I believe it is the only way to have a better life in my country. But I also have a plan b myself in case it fails. I will be fine, and my family will have no problem even if bitcoin fails.
