Exactly. If Proton does anything with cryptocurrency, it should use one of the privacy coins, and Monero is probably the best option here. Here’s how I would’ve rolled it out:
accept Monero w/ a discount directly as payment for Proton - I might have picked Proton over Tuta for this
add Monero payments to Proton Pass
integrate 2 into existing products (e.g. send money to trusted contact, pool money for events in calendar, etc)
add other cryptocurrencies (e.g. Bitcoin and ETH) and payment networks (e.g. Lightning)
But no, they instead did:
accept Bitcoin as payment for Proton
release Bitcoin wallet
??
At least it’s non-custodial, but that raises more questions because if it’s non-custodial, I presumably already have another wallet anyway. The wallet doesn’t add anything directly useful.
