I've surfed on the web and saw that online casinos are giving a good profit, I want to know if any of you invested money in a betting app or site?

I can honestly say that I have and I think anyone can try if they are curious about the whole process. It can either just be for a bit of fun, or for making an actual profit. In both of the cases though you need to keep some boundaries, for example, to never let the game be more important than the few bucks you have saved up for something else. You need to have good self-control and everything will run smoothly. Though for beginners I also always advise being super careful with what sites they use because there are so many scams out there, you can't even keep track of them. I'd recommend looking on a site like https://bestbet.ng/bk/1xbet/ to be sure everything is in order.
