Why? As an investor I don't like having everything tied to the value of BTC. I am more than happy to have two bags. I permissionlessly convert between those on the fly if I need to. From a UX perspective it's the same as a side chain. From an investor perspective it is far superior to have separate decentralised networks that work independently.

The concept of risk management and hedging seems not very prominent within the maximalist crowd. It's a huge blind spot.
