Is using Binance wallet for gambling illegal?

Any wallet can be good and safe to use as long as you don't give away your private key to the casino. Been using all the wallets I've had for casinos actually even the MEW which I would connect to a casino app. I'm not sure how safe it is but as long as I don't have huge ETH there, it's fine. A good practice to just put small money inside a wallet that will be used for gambling.
