Do you consider that kind of addiction dangerous and not good?
Abuse, addictions, and over-spending habits - all of these things result in no good.
But it seems not a very usual thing to happen in investing because investors are smart as I think. They put money for the reason that it grom more, unlike gambling which leads to losing more. Though we can say it was not right from getting into investment addiction, however, thinking that it multiply our money in the future, is somewhat of a great addiction happening to us.
You are right, anything in excess will not be good for the final result, so investing addiction must be reduced because any investment will always have a losing impact even if you have invested in top coins, a simple case for example that you have bought buy bitcoin at $ 50k the previous ATH price moment, so surely your investment interest will decrease after your assets are reduced, so don't be addicted to investing but prioritize analysis to invest at low prices and it will take a long time to wait for a market bearish moment.
