Since Bitcoin's first commercial "pizza transaction" in 2010, the price has skyrocketed by over 500,000,000%.
So, it's natural for many people to believe that Bitcoin is a massive bubble.
People may actually be paying for their pizzas with Bitcoin once again, but this time using extremely small portions of their Bitcoins.
Lots of people have heard of Bitcoin, lots of people have an opinion on Bitcoin, but surprisingly, not that many people own Bitcoin.
I've never witnessed a bubble that had a relatively low participation rate, was largely decoupled from Wall Street, and had so many people convinced that it was a bubble
