I think in 2020 the price of the etherium will be 3000-5000 dollars for a coin! from the current price it will be x5 - x10
Any big price is possible in Ethereum if we continue to help and support them. And that is possible because we all know that Ethereum is well-managed, well-established and well-organized so there is no doubt it can rise on greater values. It is new but today it is known for its being trusted and one of the best.
