Ethereum is the king of altcoins so it should be the best compared to other altcoins. I also as a holder ethereum is very optimistic about
ethereum's future in 2020. Even though ethereum's price is still at $ 248 it doesn't close may be able to go up to the price of $ 1000 in 2020.
Then if you talk ethereum for the next 5 years it must be getting more expensive ethereum prices, I predict the possibility of ethereum prices
will touch $ 5,000 in the next 5 years.
