“Do not underestimate this. Do not listen to the people who tell you that Bitcoin is just for pornographers, terrorists, drug dealers, and gamblers. Remember that they said the exact same thing about the internet. But when 2 or 3 million people got online, we found out that they are not interested in those things — they are interested in sharing cat videos, and now we have an internet of a billion cat videos.”
-Andreas Antonopolous, in ‘The Internet of Money Volume Two‘.
