>90% Core full nodes
it will be hard to explain that in fact 90% support BU
let's activate segwit
miners do their job or users will do UASF
prove it. with facts.
there is no proof for 90% support for anything in bitcoinland. it doesn't exist. except maybe greed, and i seriously doubt there's a 90% agreement on that.
edit: we're never going to reach any consensus about this scaling thing, not BU, not core, not segwit. i'd honestly be shocked to see any of them reach 60%.
