The price will depend on the price of bitcoin. At the end of 2020, maybe ETH can be worth $500?
If you look at the current market, unlikely that ETH will reach $ 500 because the current investment demand is very low and the market is not stable enough, so it may be difficult for this to happen . I think ETH will remain at the end of the year at $300 and over the next few years minimum ETH price will reach $1,000. Everyone has very high expectations, but anything can happen in this crypto market
