I think Ethereum's price will not reach that very high price by the end of this year 2018. If you based your predictions in the current situation of ethereum's price in the crypto exchanges today. Nobody will said that it will pump as much as that price, 15000$ ? Imagine that price, ethereum is hardly even reach $1000 , how about 15000$, so impossible to reach that price only by this year !
Ethereum price can't hit up to $15,000 this year. This is a fact, it can be better in the future but the correct time is not now. This year, ethereum can hit up to $3,000 and about this price.
Even this, it's good to see ethereum's positive move.
