Proton Launches Proton Wallet - A Self-Custody Bitcoin Wallet

"Bitcoin’s value to society has been hindered by the difficulty of transacting, and security concerns, and we designed Proton Wallet to specifically address both. Proton Wallet’s ability to support bitcoin via email now makes bitcoin transactions as easy to use as PayPal, while preserving the decentralized and non-custodial nature of bitcoin."
