lol. He’s a terrible person to ask.
So to add funds to crypto.com click on fiat wallet and setup your GBP account by making a bank transfer. You can also use a debit or credit card but you’ll need the bank verified to withdraw
Once it arrives buy USDT in the app using your fiat balance.
After that go to your usdt account (tether) and click withdraw. In the space to type in wallet ID go to the casino you want to play at and click deposit and copy the wallet ID shown. Paste it in crypto.com app… approve the transaction.
Job done.
Many youtube videos on this if needed.
