Cycle 3 lasted approximately 23 months.
Cycle 4 can be expected to last at least that long which would take us easily into 2016.
Cycle 4 can be expected to finish around previous wave 4 which was at 70s.
The first major bounce could be expected from 278 before end of 2014.
A spike to 173 cannot be ruled out before end of October.
Corrections almost always last longer than impulses. Markets are said to trend 30% of the time and correct 70% of the time. Superextended waves especially take a long long time to correct according to Glen Neely. Especially thinking how the subwaves and subsubwaves in this cycle 4 are extended, I believe 2016/2018 may be a conservative target for the end of the correction. By the time this correction finishes, the BTCUSD charts should become the least popular charts in the site.
The shortsightedness that some of you pure-chartists have is amazing at times. You should short and hold out till 2018. I'm sure it'll get all the way down below $100 by then. Or more likely up to $10k.
