I don't know. Properly we just can't find the peers that are on the chain that Bittrex is using.

The main reason for that is that the "wallet" has an DNS seed node (129.21.141.139) hardcoded, that is not valid anymore. As I remember well then it was Griffith who changed the DNS seed node and then compiled the windows wallet. Everything was running fine until one day his Internet provider changed his IP-adress, making the hard-coded seed node useless. He then opted for a config file with add node option (addnode=129.21.141.135) to resolve the problem with that connection. That also worked however new MWC holders always needed to ask for the config file before they could connect. Now it seems that Griffith or has a new IP address again or just stopped his node.

My last sync with the chain was on Sat May 7 17:13:22 2016, so my chain is about 1 month old.
