I did the same on another casino but luckily for me it turned out ok and I didn't loose any tokens but I would never gamble again with tokens that give out a dividend as I love passive income While people might gamble away with the dividends they get, they will also earn more tokens which will result in even more dividend later on.
I don't gamble regularly, but I will say whoever gambles regularly, should gamble on dividend casinos and they should never gamble their tokens. I don't want to mention any other website's name, but these dividend casinos are getting popular day by day. The biggest advantage is getting daily dividends which could be considered a passive income. Anyone can play in any casino they want, but general casinos do not provide anything to their players except some big casinos that provide VIP bonuses and monthly reloads. These bonuses also depend on monthly wagers and deposits. However, the dividends depend on how many tokens you are holding. So, your plan is good, do not gamble your tokens.
That will be up to them because if they think that they can increase the token amount by gambling, they will do that and try that. But they should be careful that what they want will not always happen so they must aware of that and allocate some money to gamble.
But for those wants to get a stable reward from the token, they don't have to use the token to trade and only hold it in the casino and wait for the reward. It will be an option that we should do and understand the risk so we will not trying to do the same as others especially if we can lose anytime.
Those who earn small reward will not risks their token and just wait for reward distribute. That will help them to increase the amount.
