I go for Both , Gambling Brand name and of course Functionality . because i love seeing good names but i also seek for a best function .
^ Reading by other opinions and now I am thinking about this and it is probably right.
It could be both and why not, not only focus on the functionality, it should be on the brand name too, as far as I remember, there is someone making a thread of contest asking the name of their brand and they pick a good suggestion of the brand name. It seems it is very awkward if your brand name is not related to gambling or in crypto.
I also remember this contest (the domain name of the gambling site) but as far as I remember this contest was canceled. It's very true that both are very important because a brand is a characteristic that certainly cannot be duplicated. but if I give a percentage then 60% what matters is the functionality and 40% is the brand.
