It's every developer's dream to get their coin into the top exchanges in the industry; there are many requirements and parameters, but if the branding is right and the support of many traders is there, it's possible to do that.
I'm ok with them being traded on decentralized exchange as long as the volume is good and the price is going up. The most important thing is traders are attracted to buy because of the potential.
Of course there is no doubt, in order to run we must walk first of all, because I do not see anything wrong with decentralized exchanges, in fact I think it will always be the first step for any project that is promising, they even become known little by little, as the community makes it known to more clients, then the project can advance to the next level, I am sure that in HunnyPlay they will not stay stranded there, they will look for centralized exchanges, but from what I have seen they have gone fast, and they are in a great moment, because at any moment when they become well established, investors will be able to see the token as safe and will invest, especially if bitcoin goes up in price.
It's not that they don't want to, but they prefer their own way, and this is through DEX. One reason I can think of is to save the cost of listing; TXT, BFG, and now Hunnytoken are just three of the tokens with the same model. They have their own platform or partnership for trading their token.
It is still okay that they have their own way that the team has decided to follow, and not through CEX. So long as there is access to it by the crypto community and those who are aware of it, the Hunny token will do well.
There are many casinos that have token and most of them are doing well while some are not. And the issue is that if the gamblers can convert the token to any coins of their choice and can withdraw the converted coin ot currency then all is well.
But if you converted it to the currency and you can't withdraw it then then it is better to exchange (CEX) when I first saw the Hunney token, I was thinking that it is hunneypot casino. The site is good but how their response is in the forum is one of the thing to consider. It is better to use CEX for casino token than dex.
So far what you say is very true, many of the sites you talk about have done badly, the site that I see that is very good in terms of tokens and NFT has been Rollbit, however HunnyPlay has quite a few good things, I see that they have a very promising future and I think they want to do things very well, for me they will also have good results, I have trusted some casinos that have done well at the beginning and then they become a disaster, this casino has done things better and that is why I see a future for it.
