Jihan Wu knows a thing or two about psychology. Right now I think he's waiting for nervousness to reach a certain level in the market like there was in the days just before the Segwit2x fork got canceled. Bitcoin holders were expecting a correction and that is when the Bitcoin Cash team struck.
If nothing else, what I learned from this situation is: Do not underestimate Jihan Wu and his cronies. They are extremely wealthy (in BTC), and the multi-faceted attack they carried out over the past week was fucking impressive. Old timers can see through the bullshit and can recognize what altcoin pump and dumps look like.
But the Bcashers were smart enough to recognize a couple things. For one, they know that the circulating/trading supply of BTC (and therefore BCH) is very low; most people aren't going to touch their BCH cold storage to dump it. For another thing, they recognize how thin the markets are/how little it takes to pump them, and also how the market fixates on no-fee exchanges like Bithumb.
Looking at the chart and the fundamentals right now -- Bitmex to dump customer BCH/Coinbase to release customer BCH -- I'm expecting Bcash to bleed out. But as I indicated above, the attacks will continue. I hate to say it, but when you see bitcoiners celebrating the death of Bcash, it'll probably get pumped again.
