Any crypto wallet is fine to use, as long as you can send and receive crypto. One thing to keep in mind as usual is that it supports the correct network. As some casinos will take USDT via Ethereum network (ERC20), you will lose your money if you then transfer your funds with another network like Tron (TRC20). So make sure you select and send and / or receive with the correct one. You can use an online exchange like Binance Kraken Or simply use wallets like Trust Wallet To send funds to and from a crypto casino.
