Everything is an investment, and because there is no risk-free investment all investors are gamblers!
If a casino lose players, for any reason, there will be no profit, so tokens will be worthless! So you either believe in the casino future and you invest your money in gambling/mining, you invest in purchasing those tokens (if possible), for the share of the profit, or you don't believe in all that and you stay away!
Risk is always there, many things can go wrong... but there's also a chance for success! Are you a pessimist or an optimist? Are you willing to risk and how much risk you are willing to take? Classical questions before making an investment...
There is a HUGE difference between gambling and investment.
In investment you do not have any type of "guarantee" to lose money at all. Whereas in gambling there is a guarantee that you will lose money.
So the difference is that, if you buy this token then there is a chance you may make money or you may end up losing money, but if you gamble, as long as you keep gambling there is 100% guarantee that you will end up losing money, all because house edge, sure there could be some sort of luck involved which makes you win in the middle of the situation, but at the end of the day you are talking about something that is only good for a moment, then you will keep losing in the future.
So long story short, a person who gambles here to make more chip right now, may end up not gambling and not risking and end up buying chips because it is less riskier method.
