The correct action then, is not to short BTC (which continues its inexorable exponential rise) but to short mankind, which apparently peaked around 1969.
LOL on shorting mankind. What happened in 1969?
From gold. Silver certificates could no longer be redeemed for metal after 24 June 1968.
IIRC we made it to the moon in July of '69. Also, I think the U.S. median standard of living peaked about that time.
MLK Jr. was assassinated in 1968, Nixon elected, Timothy Leary arrested. Elvis went to Las Vegas. AIDS came to the U.S. Overall the end of the '60s was a very unfortunate turning point.
But the deathknell for mankind was undoubtedly captured on videotape, thusly: What's New Pussycat?

Watch the moon astronauts first interview (beginning at about 1min25sec)
They knew the music had died and the disco era was about to be ushered in.
Either that or something funny happened on the way to the moon.
