It is difficult to say. A few days ago, there were congestions.
Lots of users have been having withdrawal issues on Polo (though not necessarily for ETC), and support tickets are backed up for a month. That is why I got off of polo.
Issues are there with POLO but I don't think so because my friend has the issue but the support people has solved his issue in just 2days. I don't know why people are kept complaining about Polo.
