ETH. Now a critical point!

Critical point for ether.
After the sellers broke the price range of $ 450-480, ETH fell practically without correction. even a strong mirror level of $ 385 could not stop the fall. But why? If you look at the history of ETH, there have never been volumes at this level. It was more of a psychological level, which once drew. The entire volume, which was at this level, is a consolidation lasting 2 weeks from March 18, 2018. Of course, there is little to stop such a fall. Therefore, the price stopped in the price zone of $ 280-310, which I predicted in the previous idea. In my opinion, this is the critical point of this coin:
 1) $ 280-310 was a good support before the air flew up in November 2017 to $ 1,420.
2) In the past, in this price zone, the position was around 3.5 months
3) Volumes on the air increased in this price zone.

Therefore, it is highly probable that a good upward movement should begin with this zone.
If buyers can break through $ 440-480 - this will confirm the strength of buyers and the continuation of a strong upward movement, where the first stop is $ 710.
 But if buyers do not keep this price zone - I'm not sure that $ 200-220 will be able to stop the fall. And if the fall is stopped in this price zone, then it will take a lot of time and volume to see the growth of the ETH.
