I like this exchange, but it is in a beta test stage and it is very often things don't work as you expect them to.
I have been experiencing very strange things, like when buying Klondikes I end up with USDE and wrong values input ending up in me buying at far to high prices, without warnings...
And now it is down and I am stuck with a lot of my coins there.
There is a somewhat rare bug when switching markets or just refreshing the page constantly.
Always check what your are trading. The information in the buy/sell boxes and buttons is correct.
We have implemented a nasty workaround to auto-refresh when its not, while we fix the real issue.
That auto-refresh does not seem to always work, though.
Also, we dont recommend using Internet Explorer 8 or lower version.
If you are wondering what is the best browser then the answer is Google Chrome.
