The bitcoin innovations that work for a currency, but not for a store of value are moving to bitcoin cash. Colored coins, weak blocks for fast confirmations, scripting, graphene... There's a lot of dev work going on. I am 100% convinced that currency + store of value > store of value. The degree to which Lightning "fixes" anything is exactly the degree to which it is centralized.

There's an anti-miner narrative that bitcoin core is selling, but in the end, the market will decide.
