By definition anyone who is trying to get you to buy stock of any kind is trying to get you to believe in the benefits of stock holding over saving fiat currency, so I think it is fair to say people are evangelizing Etsy stock the same way they evangelize Bitcoin.

No, but they are saying that bitcoin losing 50% from its high is saying something about it. But Etsy dropped the same amount in the same time period. Which is causation and which is correlation?
