its about 35 percent. poW decides the rules in bitcoin.
PoW alone does not decide anything. For those that are reading, this is classic delusional shill talk. If a handful of Chinese miners can dictate the direction of Bitcoin it is DOOMED!
No amount of miners dictate what Bitcoin is or isn't. Unless of course SegWit truly does suck and only time on Litecoin will tell 
SegWit has been activated on GRS for months now. It's about to activate on LTC and at least 2 other altcoins. It has already proven itself.but don't worry, its not a 'handful of Chinese guys'... look at antpool, there's almost 100k workers in it. and that's just one pool.
That is absurd. The number of works != number of miners.
