what you see on the chart is the way the trend goes and two support lines. the reason is to hold on profit if the trend breaks the support 1. i will not sell but i will buy more on the half way to the support line 2 and if it hits support 2 i will buy more. cause eth got strength as btc to rise.
from what i read of new upcoming projects, the eth got a future for a high uptrend even though it will hit the 500 usd and the 1000 usd, and with no fear and long term trading the eth follows the trend of btc.
