Typhoons don't affect inland very far at all..
And property anywhere near coastline in China is the most expensive as is electricity....Most heavily developed...
Most mines will be located FAR from the costs near cheaper power cheaper land.
I lived near the coast in China...And in Taiwan...Typhoons are so common everyone prepares accordingly...HIGHLY doubtful any local would put his mine op at risk.
Temp power loss will be often...but they know to protect from flooding.
Yeah I spent time in the Philippines and they build for typhoons my brother lived in Taiwan for years and they build for typhoons and this storm seems to be a 4 not a 5.
It is why I placed it in speculation. Still it is action and maybe a few farms get damaged.
When hurricane Sandy hit USA in 2012 hash rate dropped. I did okay as I had power and internet.
heck my 22 gpus doing 16gh were 16000/21000000 = 0.0007619 of the network
37,743,432,060 GH/s x 0.0007619 = 28,756,900 would be what I need to be at that percent.
So I need 2054 s9's to be the equal of 22 hd7970's times changed.
