Inside the Chinese Bitcoin Mine That's Making $1.5M a Month

Why use the profits from October in the headline of an article published in February? The cost of bitcoins has nearly halved in the meanwhile. Hope they had a healthy profit margin before.

I remember reading somewhere that some Chinese miners will mine at a loss because they can purchase the equipment/energy/cooling/etc in RMB but convert the BTC into USD, circumventing the country's capital controls.

Does anyone have any more information about this?
