It is important to never ever confuse a token with something even remotely similar to a stock share or any legal instrument conferring property. Tokens are pretty much unregulated and they carry a million pages long disclaimer which can usually be summed up in: you are giving your money but you have not rights, particularly you have no right to complaint no matter what I decide to do.
Many thought especially those newbie who got hype that if they invest on casino token they also get a share on then but actually its all the same with buying other tokens in the market. The only advantage they got is they rely on the fame of that casino, they should also see if there's proper utility created for the token so that they can call it as a good one. Lastly take extra precaution on any action we do since sometimes what we think good turns bad so thinking more deeper before investing on this is really needed to do.
Doing deeper research and how the casino owners will maintain the token, I mean the business is already there and investing for passive investment is not a bad idea, the success of the business will reflect to the value of the token, and with the staking feature it will give the investors small amount of additional tokens from time to time while holding and waiting for big events that may hype the token value and really gives them huge amount of profits.
It's your call when choosing your investment and it will be your good knowledge that will lead you or drive you to the right project to invest your money.
