Market caps in speculative, unregulated markets aren't indicators of economic relevance. Gaming facilitates billions in production on a yearly basis.

Let's watch for 5-10 years. If you're right about bitcoin, I bet its price will be much lower and you can gloat.

Luckily, we can both place our bets based on our best assessments of the future.
