It's only a bubble if you can identify it ahead of time.
Stating that something became much more valuable over a short period of time doesn't mean you know how to identify bubbles. Bitcoin is 70-80 times more valuable now than when it was at 32, and had you bought it then you would be up a lot. So, to say crypto is in a bubble today is the same thing as to predict that in a few years it will be worth less than today. Do you know that definitively ? I don't
Downvoters, since you know how to indentify bubbles, I'm assuming you shorted ethereum on margin on GDAX when it hit 400 and made a ton? No? If not, why not, if you knew definitely it was a bubble ?
Because it's very hard to figure out where the top of a bubble is, and if you short a bubble asset too long before the peak, you go broke, even if you are correct.
Well, now we are talking semantics. You don't get to claim you are correct if your forecast turns out to be wrong. So, if you identify a bubble, part of the requirement to say that you succeeded is that you can identify the top. Otherwise, your "knowledge" that it's a bubble is useless
