The fragmentation is fine. Technology is in the works to make blockchains interoperable. Look up Polkadot.

I’m aware of some of these efforts. I’ve been following REQ.

If currencies go to zero and the masses lose their money then they could lose faith in the whole system. Interop of 100+ currencies won’t matter if all have zero value.

I’m not saying this will happen, but suggesting it’s a worst case scenario.
