Unlike everyone else that didn't actually answer the question. RVN looks quite interesting and I believe a lot of the eth hash power will eventually transition to that but its going to be hard to say anything past that as i think there going to be quite a broad amount of distribution across the minable space with a good portion landing in the RVN corner.
Likewise I'm hoping ETH doesn't go fully POS for at least another year or two but at the end of the day with all the updates recently its coming this time not in theory its a reality that's going to hit hard in this space, but again lets hope for a few more years of mining ETH.
