UPDATE: A reader sends me a link to a blog entry where the blogger engages in the old "the tulip bubble never happened, thus Bitcoin is not a bubble" bit. But that is not the blog entry I was thinking about - but rather one from several years back at the height of the gold bubble, when someone made the same argument - the tulip bubble never happened, thus gold is not a bubble. Since gold crashed from a high of nearly $1800 to $1200 and has stayed there, I think we can call that a bubble now.
Another person argued we should "go back to the gold standard, when the economy was stable!" He uses credentialism ("respected Wall Street Publisher") and the ersatz mathematics to make his "point". But as I noted in my blog entry, there are maybe - just maybe - one or two bubbles that burst when we were on the gold standard.
No bubbles? You don't have to go back to the 1600's to find examples of bubbles. We had one just a few years ago in gold, a few years before that in houses, and before that in tech stocks, and so on. And in each case, the techniques recited in this blog entry were used to shout down the naysayers.
This alone, is proof of a bubble - when people say, "It's not a bubble!"
And MLM isn't a pyramid scheme, either! Ha!
