integrating lightining and other smaller altcoins could be two interesting ways to go to improve the website too.
Adding more altcoins can be good but only if they are in demand and fees is not too high as well the liquidity factors also need to be kept in mind so that users don't face any problems while for lightning network the demand is good and network has capacity also now.
Well that is going to be improvement on the site if that is actually needed by the fans and users of Duelbits. I am not sure what is the partial conversation before this but adding an altcoin means we are just giving options for the users. As far as the cashier is concern we already have plenty of options available and adding more is just options and not the improvement. An improvement would be upgrading the features that are failing to provide adequate quality to the users. Right now it seems we have fairly good UI, plenty of slots and other games to gamble on. With the time they did added sports book too that tells us how Duelbits is going with the flow and keeping up with current needs.
