Interesting but why do the developers only launch this casino just now if they have a sister company that's been doing great here in Bitcointalk, it's still ok if they have two casinos here manage by one company, we already have Bitvest and 777Casino being managed by one administrator, well it's not yet late since it's already confirmed that it is managed by the already existing casino here we can trust this one with the same trust with its a sister company.
That's a genuine question. As far as I know Bitcasino has a decent reputation (I am not sure as I haven't played there so I may be wrong). But I have seen Karl fron Bitcasino is pretty active in this forum. So apparantly there's no reason to create two copycat websites that target crypto gambling community.
Probably this question will be answered when OP comes back again.
