Self-custody is incredibly important for individual freedoms and also for the long-term survival of Bitcoin. We can only make the tools good enough and hope people use them.
Self-custody is the goal and Bitcoin Safe pushes on this front:

- For individuals Bitcoin Safe offers a wallet setup wizard https://bitcoin-safe.org/en/knowledge/setup-multisig-wallet/  to make larger savings with singlesig and multisig easier and safer to setup.
- For organizations Bitcoin Safe offers multi-party multisig tools like Chat&Sync to synchronize labels and sign PSBTs remotely: https://bitcoin-safe.org/en/features/collaboration/

Mempools aren't exactly packed, downloads for most of the cold storage apps number in the hundreds or thousands, not tens of thousands. Do you think self-custody will ever be widespread?
