I need dopamine in my life which is why I gamble a bit. I also like thriller/horror movies, I drive faster than I should, drink coffee...

That said, all of that is done in moderation.
I'd never put my well being in danger by spending too much money. I'd never attack or kill someone for money, I'd never steal money to gamble. If you're willing to go that far, you need professional help.
These guys who murdered to get money for gambling weren't just gamblers. You need to be a sociopath, lack moral standards and empathy. A normal person, even addicted to gambling would not do that.
We all DO. It's definitely why we check the price of Bitcoin every hour/every minute/every second, during morning, noon, afternoon, evening, AND waking up at midnight merely to check the price.

If it's a bad price movement = bored mood, sometimes bad mood. If it's a good price movement = dopamine reward system starts working, making you believe that you're a smart/intelligent investor.
