The fact that segwit was canceled was really interesting and shocking in the same time and have to admit very excited news specially for a altcoin holder like me. Like you show in the print-screen most of alcoins are on green and gain back what they lost lately.
Now the big question is and i will go a bit in to some conspiracy if all this segwit was not just a fake news just to raise the price of the Bitcoin on the principle: Buy the rumor sell the news!
True that. Those people who get insider news could easily long future and spot the btc future got a shor squeeze last night because people are rushing to close the position following the news. The price was up to almost 10000 usd on that snapshot.
