look at the trading volume with growth in 2017 and compare with the volume of the end of 2018, the volume grows means someone buys it.
Well, if volume grows and but price dumps then it means that there are more sellers than buyers. Of course there are buyers which knows what is behind NEM and wait for the breakthrough that will come. But there are also bots which buy and sell want drives the volume, too.
Pointless talking to those who look at these coins as just another stock market.
They don't see the bigger picture.
