The market is always inclined towards the utility. The utility of a token is based on the extent of its usage which can be attributed to its utility. Apart from this there are other factors that need to be considered for making it more appealing for people. For example, gambling tokens are free of cost and hence more people can adopt it than others. In addition to these, development teams behind tokens also play a vital role in creating more use cases than other tokens.
If there’s a utility and the site is ok, then i think investing on those casino tokens can be a big thing especially if you are also a player on that site. Though, this may not rewarding since this is a utility token and most of the time only the gamblers support this kind of token, but if you see any good analysis with that tokens then why not. There’s a big role for this utility token, their purpose is to provide liquidity and maybe this can be a big token for that site and gamblers will have no choice but to adopt it.
Much better if you are a regular player of the site as you can keep up with their updates.
You can also track their progress if you are an active player, so you will have an idea how they are doing with their business.
But if you will buy the token and just let it stake, and come back after a while, you may miss something important.
Look for other use case of the token itself as it may add its survival in the market.
Is the team looking for other applications other than casino token only?
