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.
Everything that is done overly, that may lead to addiction will definitely affect our whole well-being. That is the reason why we should do things within our control, otherwise we will be force to do things that are not right and aren’t just. However, with investing addiction, provided that you are totally aware of its risks and you will only invest an amount that you can afford to lose, I think that is valid and reasonable as investing all in will be detrimental to your health if ever you lose them all in the end.
