Well, where did I say it is btce wallets? I just posted that coins on the move as it is a coincidence with btce offline, and the ETH account on the move too. So you can post the source of that proof, I will appreciate it. Two days ago (like I wrote in this thread here) I believed it too that those are Coinbase or Polo wallets but I just cant find any proof for that. If you google for that addresses, even a Facebook entry of mtgox turns up stating that the address belongs to them (in 2014).
