I have just received a message saying successful authorisation to my Btce account from the ip address 109.201.137.162 which apparently is based in the netherlands.
This was timed at at 26.06.15 21:43.  according to the message, it was 19.43 here so presumably this had just happened. 

As I did not log in, it looks like the account has been hacked or brute forced. For me I dont think there are any implications, its an old account - I tried to log in
and change my password but they had already done that I was not fast enough.

The message from btce is from a noreply address (That really is so smart isn't it!) so I have no idea who I should tell.

That's pretty annoying, but if you have funds on Btce, beware.

Mark.
