Jihan said "he will activate BU if it reaches 51%"
Is he really so desperate to achieve his centralized blockchain but if he activates it that would be bad for bitcoin and maybe it will turn all against him. If some miners change their minds again and those that is undecided chose Segwit instead, this is just complete chaos.
LOL..how does one "activate" BU??? They are already running the client if that's what you mean.
Bigger blocks can be mined at any moment, and big blockers could destroy the SegWit chain in hours, not days. So don't worry about a forked chain because BitFury isn't going to sit there trying to mine 1MB blocks at the same difficulty while over 50% of hashing power is carrying on as normal. Even if SegWitters end up with 40%, that means blocks would take over 20 mins on average. You'd have more than twice as many transactions for the same 1MB block. Unconfirmed TXs would spiral out of control and the price of "Core coins" would tank immediately. And that situation assumes that none of the majority miners don't attack the SegWit chain. You guys are in a lose-lose situation.
Understand that the ONLY reason big blocks aren't being mined yet is because they are giving users time to figure out what's going on and pick new clients to accept bigger blocks.
By the way, they are NOT running the client as I already said. They added BU flags into their coinbase signature but all the antpool mining bitcoin nodes are showing up as bitcoin core clients. It turns out they don't actually trust the BU code, they are just using it as a leverage. Lucky for them since one pool already fucked up one block by trusting the BU code.
And as for "activate" BU in whatever form that takes, it would be nice to see because with 5000+ core nodes out there, the core node users would be completely unaware that a BU chain had started, only the slow blocks you speak of would be noticed.
After one diff retargetting things would be back to normal. You're grossly exaggerating what would happen IF a BU based forked chain began. There will be no "destroy the chain" unless there is a concerted effort from them to waste all their hashpower and generate useless blocks on the core chain - such a move would cost them tens of millions of dollars of lost power and revenue in a short time. As if the bitcoin space doesn't hate them enough, such a bastard move is nigh on criminal on a massive scale and THAT would make the value tank for all forks of bitcoin.
Understand that you are in a minority thought pattern here, defending their actions. Once 4 vocal trolls are removed from bitcointalk, it fairly closely represents what's happening out in the node space with 5700 identifiable nodes running core and 630 running BU - and that number is falling. Yes miners have a lot of power, but they cannot direct things as easily as you think to destroy bitcoin core.
Oh really? How would the minority SegWit chain even get to retargeting without another hardfork? Difficulty is adjusted after a certain amount of blocks, not after a specified time period. And the minority chain would take months to get to that change in difficulty even if miners never dropped out, which they definitely would after losing so much money.
