Small sample size, but numbers have flipped in the last 24 hours (37% SW vs 31% BU).
Yes, interesting observation. While BU's numbers seem to be inside the normal statistical variation, Segwit acceptance has definitively increased.
I think much will depend on what F2Pool decides to do (third largest pool as of March 26). Until now they don't signal neither for Segwit nor for BU. I have no recent statements from them, but they seemed Segwit friendly, although they said they would activate it first in Litecoin (where they haven't begun signalling it yet). Maybe their gamble is to stay with 1 MB a while more to drive the fees a bit higher first.
they're playing a dangerous game either way.
They're chocking the network and driving users away form bitcoin.
Even if current holders keep holding, new adopters seem to prefer altcoins over bitcoin.
