SegWit can revitalize Bitcoin while Bitcoin Unlimited can only create another wall between users.
You don't believe it? Just check up what is happening to Litecoin, they are on a brink of SegWit's activation.
The price of LTC is soaring, media attention is higher than ever and community is positively thrilled.
http://litecoinblockhalf.com/segwit.php Litecoin is only ~6% away from a major breakthrough.
Funny, because Litecoin blocks are nowhere near full. Also, they lowered the activation threshold to 75%, so we'll see if that causes pain on activation. I predict that some subtle bugs will appear shortly after activation. Then we can thank our lucky stars that the miners are vetoing Segfault.
What a sh*tshow it will be if Litecoin has to roll back Segwit...
