Gambling is wagering/staking something with an uncertain outcome. While on the other hand, investing can be said as committing to something with a calculated expected outcome, consequently owning parts of the thing you are investing.
If the gamblers only play on the site, they own nothing. It is inapplicable to investors since they own part of the shares/things, regardless of the outcome. So I believe both things should be differentiated.
You are missing the point. Both are different terms obviously, but people tend to use investing loosely as similar to adding funds which is why it's silly seeing some of ya'll trying to differentiate between them.If the gamblers only play on the site, they own nothing.

I think this discussion makes it very sick. Just like someone said above, forget about it and keep enjoying the Christmas that is our way. Let us put some money, try to chase those raffles and enjoy with Mr. ROO. 
Sick? What the heck are you on about? Every single post in this thread is obviously not related to Roobet just like in any other ANN thread. Think!
