I didn't quite understand this post, the author is very vague in his description of his investment actions. From his description it turns out that he invested in a Ponzi scheme, which is also gambling or something like that. We know that some casinos or even bookmakers allow you to invest in them or invest in the products they create. Now many casinos and bookmakers create, for example, their own tokens and offer users to hold, stake or trade these tokens. You know, trading and gambling are gradually converging and sometimes it happens that in the end we ourselves do not fully understand what we are doing: gambling, trading or investing. These are modern trends in gambling.
This same fake product can be said to be Ponzi scheme like just like you mentioned, and what I will like us to know is that, anything that has the legit version, it fake will always be there too, so I am not surprised to see a casinos being stuck up in Ponzi like scheme, but then also we should know that we have some viable and reputable casino's that have what we call backroll investment and those gambler's or investors who put their money down for this get returns on a monthly basis without any stress or risk of losing their money, casino's like bustadice have such a feature.
Between we should be vigilant when it comes to casinos products most especially anything that has to do with finances because casino's primary field is to develop games, so any other services that they render will and remain just a copycat move, if not I don't see any reason why a cryptocurrency casino will sundenly go into token development or other cryptocurrency service that generates profits.
