I will be a bit surprised if SV wins, though it's not impossible. If SV wins, I suppose it'll be only after at least some weeks of war. This'd be the most funny and damaging for BCH, though I find CSW too distasteful to exactly hope for a SV win. It'd be especially funny if one side wins due to economic support despite losing on hashrate, which is possible.
I don't see much impact to BTC of losing 5-10% hashrate in this scuffle, especially since the Bitcoin difficulty adjustment is conveniently going to happen in ~1.5 days. I also don't see much fundamental reason for the BCH outcome to affect BTC's price, though who knows short-term: IMO the recent BTC crash was set off by Jihan trying to make some point (made possible due to low exchange depths/volumes).
It seems CSW is threatening with class action lawsuits as well as mining empty blocks to stop BCHABC supporters (including traders trying to exchange BCHSV for BCHABC, exchanges that support it and whatnot) and he claims Jihan Wu allocating hashrate from BTC to BCHABC is breaking a contract and will have legal consequences. Of course, this sounds like nonsense to me. Which jurisdictions have laws forcing miners to mine a particular coin, or I am missing something here?
Another interesting statistic is the amount of nodes supporting SV:
This will be a good experiment to see hashrate vs economic support. It all comes down to if CSW can afford mining an undervalued coin while mining empty blocks to clutter up ABC and cause reorg.
