The US pool is more profitable, but has frequent disconnects. So if you have a large ping to the US server, or cgminer is unstable because of the disconnects, use the EU server. Otherwise stick with the US server.
The EU server is constantly on DOGE for the time being.
The disconnects will be fixed within a few days. They occur on coin switches, and I'll be rolling out some new code to do it cleaner.
The master has spoken...if its more profitable then I will switch back to the US server...
Haha, yeah I have noticed it seems more profitable despite the disconnects, but I am using the recompiled version that reconnects faster.
