I am also baffled about the use of the terms investment here too. Is it the money use for gambling or money used to invest in a gambling platform which in return will give a person some passive profit in depending on the platform profit?
I do not think that funds used in gambling activities (betting and wagering) can be called investments.
Well, It can still be considered as an investment since you're using your money to gain although in a much risky way and no assurance at all. I don't think this is a big deal since we have our own perspective regarding on the money we use to gamble. If it's an investment for you so be it, if it's a throw away money, that's your decision.
Anyway, holiday is near and long vacation is approaching. What slot games from play n go can you recommend?
