To me this makes sense, we also need to take into account that a great deal of the coins that we have in this market have nothing solid behind them and as such it is natural they are extremely susceptible to the manipulation that is going on in the markets, but when it comes to casino tokens we know there is a company behind them which can back up the price of their token with the number of clients they have and with the profits they have gotten over time, so it is not surprising that casino tokens seem to be more resistant to the fluctuations in the market.
I don't like to discourage anyone to invest their money in anything they believe is good for them, but they should always know that they are risking higher in some cases. Investing in shitcoins/tokens is not my thing irrespective of the companies behind them, I had a lot of experiences thinking that a token would rise because gambling or trusted companies are behind them, but I lost over 85% of my money in most cases. So, backings by any company or section are not the case, only that if the trader can afford to lose or risk higher, they should go for it.
