I very much doubt that the price for eth will be $ 2500 this year. The maximum that we will see is 1300-1500 $. If the price is above $ 2000 - I will be happy.
Actually we never know so we should not underestimate ETH, based on my study, ETH has the most supporters and the most advance technology.
Bitcoin might be the most popular now but it's easy for people to transfer their money to altcoins once they feel it is gaining the attention of the many.
