Losing on gambling is much more faster than on investing on the house but talking about the speed on gaining money then playing gambling do really have the edge.Its your own choice by the way since we do have our own free will.
That is so true, the more risk it has the more chances of getting big return but yes, there are really people who have lesser risk appetite when it comes to gambling. I would highly advice through to not use more money that you can't afford to lose with gambling.
I think most people agree it's impossible to win on long term by gambling, so it doesn't make sense to play a lot knowing sooner or later the loss will start... At least investing you can have a profit on long term. It's good for who wants to make profit from gambling, but for who doesn't have financial problems and is playing for fun, go ahead gambling a lot... It will depend your intention here: profit or fun.
