Bitcoin maximalists reacted negatively to the news of Casa unveiling a new app with Ethereum support.  The custodial service has been storing Bitcoin since it started, hence, BTC proponents feel betrayed by the move. 

Casa will unveil the new version in January 2023, where users will have the luxury to store both BTC and ETH, sign up for new membership plans and unlock funds through a 2-of-3 multi-signature feature. While the firm’s first CEO Jeremy Welch had discussed plans of bringing multiple cryptocurrencies, most of its users felt the platform needed to maintain its Bitcoin-only status.
