If you could combine the best from both worlds and accept more cryptocurrencies and fiat payment methods it could only benefit your user base.
You mention credit card payments only for residents of New Zealand, but what about the rest of the world?
Many online platforms and Bitcoin casinos support electronic payment services such as Skrill and Neteller. This could be one direction to go as well.
I know it's still in the early stages, but are there any online sources about Bitseno? I couldn't find anything.
also, does it mean that they will require KYC for all players or just those that will use fiat currency? because normally, if it is fiat-based, KYC is compulsory. waiting for more updates on this site.
and as Bttzed03 suggested, while waiting for the launching of the site, better purchase copper membership so you will be ready to launch your new casino, not only with texts but along with visual images.
