There are few gambling tokens wherein market prices gone up. Most of the time, the market value of gambling token is either stable or falling. Stable because its supply si continuously circulating because it id a token being used in a gambling platform, demand won't be that high because on the usual, the token supply is huge. To fall on the other hand has a tendency especially if the gambling platform itself did not manage to attract the attention of many gamblers. Much better if you would directly invest to the project itself thru 'shares' if you are really looking for profit from investing in gambling related projects such as with what I have tried doing (earned some profit but BTC affected the profit. But I won't point finger to other factors, I also made some errors, but the idea is there already). Here's the thread (not as updated as before, quite busy these days but I'll follow it up maybe next week or month):

Those who gone up must be from the popular casinos. It's hard to ignore the tokens because they can have certain benefits and investing on them is another way of showing your support to the casino that you love. Not just gambling tokens but the movements of a common crypto are also like that. They are not stable in short.
This is normal and this is not bad but it was an advantage because it enable us to buy low and sell high. Some of the gambling tokens have a huge supply but a casino can add a burning mechanism to greatly lessen the tokens supply. If you don't want your profit to be affected by btc then you better convert them into stable coins. For some casinos, they are giving returns in stable coins, which are great.
It is good to should you support to casinos that you like and you can always invest in them if you know how the project works and if they have a good team that can make the project go to the moon, nit blindly investing in project that will end up becoming a rug pull and all your funds will be gone before your eyes.
The reason why many person do not like investing in casino tokens is because they are not always listed on a popular exchanges where investors can buy and sell there holdings without any challenges.
