Yes. If Yellen is so competent as she seems to be - to many, including myself - I'd like to listen to her explanations why arguments in favor of cryptocurrencies aren't good enough. After all, there are some ideas behind Bitcoin, some explanations of benefits, which apparently bring some people to cryptocurrencies even without get-rich-quick hopes. What are Yellen's answers to those requests which led to creation of cryptocurrencies?
