BUggy is dead. If the miners go with their attack, they will get fired via PoW change, and it will prove that they didn't care to cause havok on the network they were direct attackers since they KNOW going through with this kills bitcoin network effect and price.
I don't think so that BU is dead, in fact it is already on a exchanger (correct me if I'm wrong), it is just Bitcoin is still the number one amongst all the Altcoins here in the cryptocurrency world, that is why this BU is not that popular or in demand. Most of us are still supporting bitcoin, our hopes are still on bitcoin, because we know that Bitcoin is the only one that will lead us to success in the near future.
Especially those people who are saving bitcoin everyday, keeps on holding it and waiting for the right time to convert it to have a huge profit from it.
