also keep in mind that segwit is still not locked in
viaBTC pool announced they won't signal and their hashrate went up
https://twitter.com/ViaBTC/status/856487968193642496rumour is they have bought many of the new miners from jihan and they could still push segwit back with that
this show is not over
The amount of hashrate ViaBTC needs to stop segwit is enormous and unlikely to be possible for them in 24h to do that. So no worries about ViaBTC, more worries for any other pool to stop signalling for any reason.
