On the upside, there are key resistances near $175, $177 and $180.
If there is an upside break above $180, the price could recover towards the $185 resistance area (the previous support). Conversely, a break below the $165 support might push the price further lower. The next key support is near the $162 level, below which the price could accelerate lower towards the $155 level.
Looking at the chart, Ethereum price is showing a few signs of a corrective increase above $170. However, the price must clear the $175 and $180 resistance levels to continue higher. Having said that, the main hurdle for the bulls is near the $185 level.
