Nothing is assured when it comes to future aspect of certain coins or projects and it would really vary on the development and simply with the demand.If they would really be listed on main or known platforms
or exchangers then expect for its price to soar up at least but in the end of the day which support for the project would be the main key for it to sustain with this unpredictable market.
I dont have any gambling based tokens/coins in my portfolio yet we do know that only few do really see some positive input or views for these coins to soar up its value but
well this is a personal choice.
It's a personal choice indeed, people who invest to casino related assets mostly aiming for passive profits, they are all okay with waiting they will continue to hold till the market for the coin grows to their target value, not that quick as you mentioned, the developers needs to work with bigger exchange to attract more traders to invest and start hyping the value of the coin..
Not easy to take the risk as there's also a high chance that the value might collapse if interest with the development won't gain
investors trust.
