I recently (yesterday) calculated[0] that Ethereum is roughly 64% of the GPU mining market by power. That's a lower bound - it's likely much higher, maybe 75+%.

I recently (yesterday) calculated[0] that Ethereum is roughly 64% of the GPU mining market by power. That's a lower bound - it's likely much higher, maybe 75+%. Hybrid POS/POW is expected in the fall and will likely come with a healthy drop in the block reward. Following that will be full POS (2019?) after which, at least on the main Ethereum chain, there will be no mining. I'd like to see the block reward dropped much sooner but that's a long shot request.
