Re: Opera now lets US users buy crypto with Apple Pay or debit card

Is the built-in wallet open source? If not then avoid using it. Remember what Andreas Antonopoulos always says: "not your keys, not your bitcoins".

Users do control their own keys with the Opera wallet.

The Opera browser is partially open sourced since it's Chrome-based, but most of the UI and presumably the cryptocurrency wallet are not.

I would especially avoid the Android version. The Android wallet relies on the Android keystore system, which has been broken several times:
