There is an error in the graph: The downtrend he describes as "Wave 2" was much shorter.
Bitcoin hit the low (the dip under $200 between the 2013 bubble and the 2017 bubble) already in January 2015 (
see this chart), not in 2016 like in his graph.
I don't know if this invalidates his prediction - it could be the case that his predicted high will already be reached in 2017 - or it has already been reached. Wave 3 is often the longest of the bullish waves, never the shortest. So actually we may be in Wave 3 for almost three years (Wave 1 was 4 years long, if we follow his graph, although in 2009 and 2010 there were hardly any trades, Bitcoin was "play money" then).
@d5000, it looks like there's actually no error. The author does point out the Jan 2015 low and explains why he extends Wave 2 until June 2016:
"This time it took 13.5 months to reach what I’ve labelled as the Wave 2 low in Jan ’15 at $152.40 (or 2.7x the 5 months it took for Wave ii to make its low).
So let’s use the factor of 2.7 to look at future wavelengths (durations).
If Wave ii lasted 11 months, perhaps Wave 2 would last 30 months (11 x 2.7).
That would take us from the late Nov ’13 peak through to June ’16.
...
However, as we now start to flirt with the Wave 1 high (in USD terms at least — most other currencies have already exceeded it) we can begin to postulate that Wave 3 might have started in June ’16 on its merry march upwards."
So i take it for what it's worth, i think Wave 3 is accurately stated to have started June 2016.
His graph shows that Wave 1 lasted a bit over 3 years, Wave 2 a bit under 3 years, Wave 3 is predicted to last a bit under 3 years according to his chart, so that may put us at 10K by end of 2018 beginning of 2019.
