Unikrn have a normal Malta gaming license for gambling with FIAT on their platform. Malta hasn't actually given out any "sandboxed crypto licenses" yet to anyone as its still in very early consultancy stages atm. Even when Malta do finally agree to the framework of the sandboxed license its always takes a very long time for the MGA to actually put these things into practice. The MGA is known as one of the slowest gaming licensing authority in the world.
