This is just a picture of an empty office, I don't see anything that connects this particular empty office to any particular entity. You might as well claim this office belongs to Avalon, Bitfury, or Huwaei. It's like people selling miners without their username/date--it's not very strong proof of anything.
Any thoughts?
Yes, it's asicminer office (room 1317). I can gurantee, I've been there. Before the holiday, there were many young guys working there.
And you know what? The ShenZhen office of TSMC is downstairs (room 1201) !!!
