Everything is working fine as far as I can tell, it's just that it has become cool to hate ETN nowadays. Miners have stopped mining it and some "hodlers" who were hoping to make easy money in a short time have given up. That's what I can read from the charts.

That was necessary though, now at lower prices than ever there is a chance for new holders to buy in. If you are worried about the price, you'll just have to wait a bit longer.
I'm more interested in having ways to spend ETN for services.
