Great post @shortsegments.

And before we buy financial assets at discounted prices, crypto included, make sure we don't have debt, house debt may be the only exception.

I think people buy financial assets, or any asset really, at high prices, is partly because we equate price with value. Your lemming example, wisdom of the crowd… because if the crowd is buying it…chasing the price up with more money…it must have value.

The funny thing is, groupthink (people thinking the same way or doing the same thing through collaboration) is sometimes good and sometimes bad. Buying into financial bubbles, it's bad…trying to win a war, it’s good. We as humans need to distinguish between the two and when to use groupthink and when not to.
