Theres a lot of improvement which just went live. And you might have time to read a new blog entry via
bitvest Blog . Who knows what you may find there.
I have known bitvest for a long time and have tried playing in it several times, to be honest, since the beginning I knew bitvest, the UI/UX has not been much different from year to year, while almost every month new online gambling sites appear with the updates they offer, I think @lightlord should think in that direction because even though maintaining the old concept is good, following the development of the times for a gambling site is a must so that users are more comfortable every time they play.
This is what makes them different with the other casinos, bitvest keeps its traditional/classical theme instead of doing a big update to make it modern look like most other casinos. There is nothing wrong with the classical UI/UX, at least there are few other casinos with classic UI/UX such as crypto.games and coinroyale. Improving/upgrading the site without removing the classical UI/UX is possible, they can keep it but they can add much more modern features and add more games.
