in terms of kyc, as a new player, better not be strict for now. we can understand they have license but to attract players, they should not be very strict for now. considering that pvp concept alone is hard to sustain.
It's too early to say though that this kind of business will not survived. Maybe it was not that popular, but if casinos specially big ones will carry this one then I do believed that it will also take the gaming industry by storm.
Just like what we have seen in crash games, before nobody wanted to play it, but in 2-4 years, many platform as carry it and I will say one of the favorite games because of the rush that you can get out it.
