How do you know this is AMTs bitcoin address?
If it is then holy shit.
Tracing this wallet around might not be a bad idea. Find out who it belongs to. Blockchain should be able to clear that up.
FYI based on blockchain it does not appear to be theirs.
Out of curiosity What did you see that made you think that isn't their address.
I looks to me that the 1rst deposit to that address was 1/30/14, coincidentally about the time they got the chips. also the hash power appears to ramp up and also there are several large deposits from other groups of addresses, as if miners were paid to a unique address and then transferred to this one. That is what I'm seeing but not that experienced looking at the blockchain.
I would hope that ALL mines being sold are put to work for at least 1hr as aburn-in... All my Ants were ran into a Bitminetech wallet for 2hrs. That bit is stored in perm memory, when ya reset to defaults - same address come up.
