Honestly this was their initial promise when the community was super niche, it was two things:

- Normalized money transfers independent of the regular financial system

- Reducing currency interchange fees

Bitcoin was suppose to be this electronic ledger store for valuation to facilitate these things, as I recall.

Really got away from itself

Stellar could be this open-network/protocol for transferring value. I don't see a lot of developers talking about it, but it's really really a good tool for this use case and i think it will be :)
