Sorry, I don't believe proclaiming "Bitcoin is a bubble" is a "well-measured criticism" of Bitcoin. And people taking time out of their day to make such baseless claims are coming out of the woodwork lately.

When the iPod was announced, people frequently commented on purchasing apple stock, or how you can't go wrong purchasing apple. No one was calling apple a bubble when taxi drivers were making those statements.

Sorry for speaking up against people who make baseless bubble claims.
