Investing in casino tokens is similar to investing in gaming tokens like AXS, ATLAS, or ILV. They can't be considered a long term investment and is only profitable during their hype. They are also centralized so there is no guarantee that they will survive for many years and if the company owning them shuts down, the token will be abandoned and its price will definitely lose value.
We should avoid investing in centralized tokens because there is no guarantee that the tokens will survive in a bear market, even the top 10 coins even experience a decline and there is no guarantee that they will rise once the market price recovers. Moreover, casino tokens that have a lower investment interest than other tokens will be very vulnerable to investment.
