gotta love the people that zoom in on charts. and then draw meaningless lines
take the chart quoted above. that bottom black line is meaningless. because it is not attached to any price data related to the lows.. yet wants to define what the lows should be.. (very strange methodology)
what is done is they lined up the random speculative highs of the short period and then threw in a line below that parallels the highs.. it not attached to any bottoms of the last year.. also the 'scale' gap from the top line is not a justified amount either.. who chose the scale of the gap between the two lines..
What OP considered in this chart is places (high or low) where prize actually touched or retested from due to the activities of the other parties being the bulls or bears (depending of the prospective of analysis up or down) came in pushed prize back to where the candle closed on that period.
in short yes ethereum will crash its value when it POS's but bitcoin wont crash to anywhere near the same scale
About the fall, can we say it's what's happening right now and it's hoped to continue... its really bad seeing this blood stains in the chats but, the buying opportunity is set!
