@subsequential: this one. maybe you missed this part "An easy way to cash-out is coming soon. In an upcoming release, you’ll be able to convert your CELO into a stablecoin using MiniPay, making it easier to use your rewards in the real world. In the meantime, you can access your security key in Settings of the relevant Opera product"
