No body knows for a fact what is happening with this coin, but I think that we really should not worry so much about it. I believe that whatever it is that is happening now is for the good of the market, and very soon we will have cause to smile again. Ther's going to be bull in this market again, just trust that.
Most altcoin drop in several months ago and its not ethereum only. If we see on market cap value, its drop more than 70% and its describe that most coin in market drop the price. I am prefer holding ethereum for long term because its good coin and used by most token in market
