Why does it takes so long?
We need faster confirmations.
Percentage of
blocks signalling SegWit support should reach 95% In order to get SegWit implemented otherwise It won't happen. It's being like two months without any significant changes on the chart , I doubt we will ever get there but as said above that won't make transactions faster but LN will.
It can be a long time until something be implemented but it's a good thing too, at least we will have a concrete decision with the agreement of most supporters preventing the bitcoin to split in more different ways, it could be worse for bitcoin as the price could change a lot.
There are much to be discussed yet and maybe more solutions can arise to be discussed too.
