Just so you guys know USAF is cancelled. Miners finally realised that this would be risky to let USAF happen.
This is why all major mining pool started to signalise SegWitx2 yesterday, currently, we have more than 80% hash support for this proposal.
Everything should be fine in hopefully August 1 we would have upgraded chain with SegWit running on it - and withing next 6 months hard fork 2MB will be activated.
USAE was the big counter option of the august 1 conflict, right? Is there somewhere where we can read the cancellation/cancell report/statement? This should be quite a big breakthrough then, isn't it?
