As far as I know, any reputable casino has similar additions to the rules. And Empire added this information to the Terms & Conditions for a reason. I am 99% sure that Sportsbet or BitCasino already had experience with these types of deposits, so Binance resorted to a similar interpretation of some terms in order to protect themselves from possible uncomfortable situations. Empire is still a small casino run by a small team, but looking back in a year you will realize that the small but continuous steps they take will allow them to take a sizable share of this market.
