70% is still not good enough, right? If I am not wrong, then we need a 95% consensus to implement Segwit2x. This will be extremely hard to achieve, as some of the mining pools have remained firm in their opposition to Segwit2x. Anyway, it is good to see the proportion rising from 40% to 70% in less than a month.
In practical terms, once support hits 50%+ the odds are it will snowball. The 95% was for segwit alone. The NY Agreement was slightly less. August 1st seems to have put pressure on the pools to signal.
Every think will be first time. It's first time for that just 70% but it will be increasing day by day. After 2 month it will increase as your happyness position.
