Is Protonmail still popular? I remember that there was a boom in 2016 and almost every privacy-oriented guy was using it. Is the situation still the same? I haven't seen a proton mail address recently.

To be fair, I think it would be better if they prioritize improving their current products instead of creating a new Bitcoin wallet. There is no single reason that will push me and many other people to use Proton Wallet instead of Electrum and Sparrow. If Proton Wallet was a software wallet or an airgapped hardware wallet, I might use it but it's a web wallet, it's no safe choice. Despite the fact that it's open-source, it's still a web wallet and it's not a smart idea to use it but I believe it will definitely be better than blockchain.com if that's the case.
