I prefer it to be a peer to peer cash IMO, that's more close to the current bitcoin system and it's very idea IMO.
People keep saying that yet nobody provided a single definition of P2P Cash. I'm still waiting for a clear definition so that discussing would make sense.
We should be able to come up with a reasonable platform that can do both without jeopardizing security, or usability. Its just a matter of getting the right minds working on it, and time. This is going to take time to create.
We already have a platform, that's the issue. You can't fundamentally re-engineer Bitcoin from scratch anymore.
I think it will end up as a settlement layer with other better faster tokens taking the currency role.
You can't really know that.
