There was word that their gambling license only allows for FIAT so far. A license including Crypto is tried to be acquired but I haven't heard any news on that for some time. Also I don't know if the converting deposited FIAT funds on their sites to BRK is still a thing. For now some marketing and work on stuff outside the actual wallet and base blockchain tech is done by the team and that's more than can be said for most coins, so I give BRK time to proof itself. I'm in no hurry with this (small) investment.
