This is difficult to reach 300 usd for eth in the end of 2018. We are already 2019 but still eth is on the baseline which 100+ usd per eth. The problem is that Eth is a dump and pump crypto. You may see a good market price increase for eth but in the next few days eth will going to dump. This is the cycle and I had observing this from.the last year's market price movement. Though crypto now has made some indicatoes of the comeback but still it is not the basis that comeback will going to happen. It may take some time before it will going to recover.
