Don't stress too much mate, it will bounce back.

I don't know too much about the fundamentals but could you explain a bit more?

Also there are quite a few coins which have taken a hit the last few weeks, I'm in same situation as you are on some of mine. I think it's due to the upcoming fork, this has made the price of bitcoin drop and this in turn takes other coins with it, so just don't look too much at your portfolio until the end of October when things should start coming back up.
