What a sellout. How can you write a book about how bitcoin fixes the financial system, not your keys not your coins, blah blah, and then endorse paper bitcoin products a year later.
Lyn has never been a rabid Bitcoin maxi. She's a macroeconomist who likes it as an investment because of it's fundamentals. And "paper bitcoin" is inevitable and necessary for the banking system to be able to integrate with the Bitcoin network, whether we like it or not.
If you want countries and businesses and the entire world to use Bitcoin, you will not get them all to switch overnight and abandon everything that has been built. You need to allow them to integrate and get them hooked. It's a Trojan horse.
