Would you consider bitcoin a failure if there is no way to scale the self-sovereignty guarantees of the base layer to 1 billion users?
I think as long as the game theory holds and Bitcoin replaces fiat as the global reserve currency, then humanity wins.
It may turn out that we need ecash for the last mile of money transmission, but I'm not ready to abandon lightning for fiat mints
Definitely. Hopefully the lightning doom and gloom will blow over. I certainly find it useful.
Anyway, thanks for asking the OP question and starting this whole discussion. Always come away from these with new understandings.
