Interesting point for an asset to be in a bubble:

• "When any asset moves above the ability that the average person to acquire it"
• and "it is widely held".

I would like to add: when everybody is talking about it, even the cabdrivers, it is clear sign that this asset is in a bubble.

Great video.

What do you think about it?
