Until when ethereum will continue to decline, will it touch at the price of $ 50?

It shouldn't have fallen like this.
December this year is very different from December 2017. The situation is reversing.

Hopefully it will go dipper so as I can buy more for ETH. ETH is a good investment next to bitcoin. For me saving and holding ETH is very profitable. This coins is very active in the market and is widely used by many ICOs and project in the crypto business.
