Adding new info to Finance Sector in Economics

Hi,

I really enjoy the lessons in the finance sector and other economics topics. I was hoping if a video can be added to possibly the money supply (M0,M1,M2) section or wherever else is the best fit for a video or two on bitcoin and how it will affect lending/finance. It's a new, emerging field (fintech) that will be useful going forward and I was hoping Khan Academy can tie in some of the topics covered for business to that new field.

Also, I wish the accounting section and other miscellaneous topics in inflation etc. can have more practice questions similar to structure/style of the microeconomics and macroeconomics sections.
