Yes it brings up a valid thing to look at on the Bitmain, Avalon and other BITCOIN miners (disabling remote Telenet access) but....
Read that article and it is clear why the BTC area of this forum gets pestered with so many altcoin queries: Time and again the article talks about BTC miners in China being taken offline and then -- proceeds to finally say that they are LITECOIN miners.
It is certainly possible all of these miners are pointed to the Litecoin network, considering how the machines appear to refer to “Thunder” hardware. That would identify the hardware as ZeusMiner’s Thunder X3 miners, which are used to generate Litecoin income over time. The firmware located on the identified devices seems to confirm as much. These machines combined can generate around US$1 million in income every single day.
Of all the idiotic 'reporting'... good lord...
