Ecash is not crypto. It's a minted token backed by anything. People will choose their preferred mint backed by their preferred money. They can use Keychat with any money that has a custodian running a Cashu mint. Even a mixture of different assets while we're at it. It's just that now bitcoin-backed Cashu still dominates.

Free attracts spam, which is by definition not sustainable. Is requiring organizations like signal to self finance by dumping a token on retail, and seeking grants in perpetuity sustainable? Signal does have a subscriber program. I wonder what percentage of staff and server costs, spam mitigation costs of a signal service are covered by revenue.
