There is no doubt that the ethereum may really gets over $440 because of the massive pump up that we are seeing right now and it is a good sign that the bullish if the altcoin is getting stronger than ever.
You must also consider the halving that will happen soon. It makes the ethereum goes high since its price is dependent on the price movement of the bitcoin. The bitcoin is continuously going up this past few and the market value of ethereum has been affected by it. Sooner or later, it might reach that kind of price if the value of bitcoin rises up also.
