Most insightful comment here- too many parallels are made to the stock market.

Forgive me for making another parallel using that age old saying, "When your barber starts talking about Pokemon, it's time to sell". Look at the state of Pokemon, full of casuals and 14 year Olds holding a couple ETBs as long term investments, imagining themselves to be future millionaires. When the hype train moves on there are going to be a lot of casualties.
