1. BTC breaks the downtrend line with a rally to the 50MA
2. Price reverses at the 50MA and goes down to retest the downtrend line
3. The downtrend line now acts as a support, we make a higher-low and it all begins again
P.S. IMO The BTC cycle seems to accelerate itself (either linear or exponential), so I suspect that the will complete faster and the new ATH would be lower than the one suggested on the chart!
BTC seems to be heavily overbought, but big volume kicks in, so the chart above can only be used as a reference to last bottom and the following bull run. Such reference can provide 1:1 accuracy or a totally wrong prediction - in both cases comparing present movement with a historic one can be used to draw some conclusions, that can provide helpful background to our other trading mechanisms.
For now, I expect price to reach the 50MA (5700-5800 area) and will watch price-action around the MA to see if it reverses or we break it upward.
