It's not about this announcment, it's just because the WAR between Bitcoins Core and BitCoins TX (another Module of Bitcoins introduced with 8MB Blockchain instead of 1MB) So now the problem here's that one of BitCoins Core or BitCoins TX will take over in some time and rate would get stable ahead then, There's might a chance that BitCoins rate would drop even more during this war.
Insightful ..... so then bitmain just let the news out to ride the crash rather than being wholly responsible for the drop. That'd make sense.
Still, there is probably a good amount of the drop (even lack of bounce) factoring in the implications of the increased network hashrate that the new chip'd represent (as is the norm).
