775 price area is my primary target for the completion of five waves. The target is based on 1.618 Fib extension of the wave (A) rise and wave (a) retracement. It's possible the high has been reached (alt count) but this makes wave (4) disproportionately small relative to wave (2).
I believe this is a good opportunity to take some profits and watch for a short opportunity after an impulse down wave.
This correction may seem massive but keep in mind bitcoin introduction goes back to 2009. Bitstamp charts do not have price data prior to 2011-08-15. The bubble that burst in 2013 was a clear five wave rise. Bubbles have long corrections. Time-wise we're at ~2.5 year correction vs. a 5 year rise. I did the math and a little over 3 years would equal 61.8% correction in time.
