Seems mighty unlikely since SV will have to reorg 685 (557452-556767) blocks since ABC's checkpoint checkpoint
Everyone seems to think they have to reorg the whole chain. Why do people think that? Reorg like 10 blocks (repeatedly?), and already you have done much damage. Miners miss rewards etc
So you know their battle plan then? What if they use a war of attrition approach atm until unprofitable mining is reduced more and then attack? Or maybe they still gather their forces?
