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.

well
its true for basic,
but all of altcoins has a fallen too.
why ethereum is very drop than other top 10 coins probably because on last year, people buying so much for investing and this year, dev sell so much.
also we on downtrend make price dropped more.
