If you don't know, then why entitle your topic with a statement?  At least qualify it with a question mark.

This is what I'm hearing but I cannot find anything definitive. Is this why BTC price has started moving?

it is the same amount as it was before, nothing has changed. that 4% is just the simple change up and down because of the way finding a block works. it is not a guarantee to find a block, it is a chance!
sometimes you find 420 blocks sometimes 425 and sometimes 418 for example.

UASF to activate Segwit is picking up needed momentum. This would certainly cause a spike in price and confidence.

 Hashrate is usually calculated based on found blocks so it probably also fluctuates with luck... Though this recent variance is greater than any since inception.

Do you have more details? Which feeds/posts are making you think it's "on the borderline"? I'm not a heavy Twitter user, that's why I'm asking.

The only reason there could be a step forward to Segwit adoption is a possible UASF. I don't consider it the best idea as of now (because of the chain split danger), but maybe it's the only way to really move some pieces on the chess board (I still favour this solution, but it seems to have lost traction).

No, there's actually been forward progress on activating segwit at last. The discussions have all been private at the moment between pools and some mediators but the twitter feeds are starting to leak information about how much progress has been made, so I retweeted one of the relevant posts.

Interesting way to downplay its relevance to segwit activation, but okay, you make of it what you will. Time will tell now.

I cannot see SegWit ever being signalled, because these groups are way to far apart. I also cannot see Bitcoin Unlimited being implemented for

the same reason. They will have to come up with something new, and just use SegWit on other Alt coins, like LiteCoin. It is a pity, because it

solves other problems with Bitcoin too... and not just a slight Block size upgrade. 

I was somehow shocked to see the title but upon checking, we are far from getting SegWit activated. There would be some issues that would be addressed if we got SegWit through that cannot be addresed by the proposal of BU.

Checking the tweets of some devs that I follow, it seems that something is happening in the background. Negotiation towards consensus or nah? Sometimes I'm inclined to think that another alternative could be plausible and could be a mixed of BU and SegWit, but what do I know?
