By The Way...to get back to the hobby-horse I've been riding on this thread:
#1. Gold in the later 1970s went through a blow-off bubble that ended in January of 1980. The carnage was held at bay through most of '81 but came back with a vengeance in 1982.
I did some poking around and found this Fun Fact. If you had loaded up on gold in the quiet time after the '74-76 bear market (say, a few months after America's 200th), and if you subsequently did nothing but HODL that stake, you would still have had a double even at the worst of the carnage in '82.
#2. YHOO, of course, was one of the biggest stocks participating in the rocket-ride Internet bubble in the late 1990s: the peak of that bubble came in March of 2000. As with gold, the carnage was contained for some time but burst forth anew in '01 and didn't fade away until early '02.
Now here's a Fun Fact about YHOO. If you had bought in the quiet time in the summer of '97, a little after the hot new contenders of '95 had had their stocks beaten bloody, and again did nothing but HODL subsequently, at the darkest post-bubble-carnage days you still would have had a quadruple.
And The Lesson Derived From The Above:If you buy an asset that's suspected of being a bubble when its price action is quiet, particularly after a false bubble that ended up only being a regular bear market (
er-ahem),
and don't monkey around with your hold, that asset can be swept into the worst kind of bubble - and you'll still emerge with a decent profit even after the worst of the post-bubble carnage.
But in order for this plan to work, you have to buy quality and do nothing but HODL. Needless to say, Bitcoin is quality.
...but the HODL part will be a real toughie once Bitcoin becomes smokin' hot...
