The biggest problem has never been self-custody it has been usability. If I can hold my own assets, why should I have to move them back into a bank account every time I want to buy something? I feel like the missing piece is a way to keep full control of my funds while still being able to spend them as easily as using a regular card. Maybe I'm asking for too much but this feels like the future I signed up for when I first got into crypto
