Each month we put a lower target for ETH. Because we realize that ETH is very difficult to go up in 2018. May target 15000$ but now target 500$ for ETH at the end of the year. To reach 15,000$ then we need to wait 3-5 years if the crypto continues to grow or if the market continues to saturate, then we need to wait a lot longer
I also once thought that ethereum would rise slowly and continue to strengthen its price position. But reality proves something else. I don't know whether ethereum was able to reach prices as high as $15k or not. But I'm very difficult to imagine if that could happen. If that is true how much is the increase of ethereum itself. It seems impossible, but many people expect those impossible increase.
