I can't give a clear picture of what will happen to the price of Ethereum by the end of 2020.. but if we can learn from the wave of changes in the price of Ethereum, then we will find a positive trend at the price of Ethereum in 2020, hopefully, the positive trend is true for Ethereum until the end of 2020.
Well, its only speculation which means it doesn't have a correct answer. But, it can influence to the crypto community if it gives a positive to a certain situations like supporting the coins. In that way, probably some investors and traders will have the interest to focus on it.
