Blow off top in 2017, need to have capitulation yet and have even hodlers doubt themselves feel long, intense pain and want to die, then "slowly" (relatively) build back up to just go parabolic again to 100,000+. Upon reaching 20,000 again I wouldn't doubt a sell off to 15,000 but then shoot to the moon, maybe 500,000, then crash to 50,000, rinse and repeat.
