# The rise and fall of Bitcoin

Excellent insights (and context from economic history) from The Economist about the rise and fall of Bitcoin!

Investors in Bitcoin are learning some very old lessons

# More on Bitcoin specifically and cryptocurrencies generally…

For more information concerning Bitcoin (other than the *Motley Fool *articles that I posted a few minutes ago), I recommend reading the Wikipedia article at https://en.wikipedia.org/wiki/Bitcoin. Technically, Bitcoin is an “application” of so-called “Blockchain” technology. Of course, I wish that I would have had the foresight to have purchased (for that matter, even “mined”) Bitcoin starting back in 2009, but such is the nature of uncertainty – what may seem “obvious” now seemed borderline silly back then.

The level of volatility in Bitcoin spot and futures prices can be quite breathtaking at times. Indeed, daily volatility of Bitcoin is roughly ten times the daily volatility of the SP 500 stock index (see WSJ Daily Shot, 11-January-2018). While there may be some entertainment value in buying and selling cryptocurrencies in the spot and futures markets, these instruments are clearly not suitable for most investors.

For more on Blockchain, I recommend watching either NYU finance professor David Yermack (cf. https://www.youtube.com/watch?v=Irc-VMuUs3c) or Duke finance professor Cam Harvey (cf. https://www.youtube.com/watch?v=G1tVnXTcDBU) – they are the best of the best finance experts on this topic.

# Credible, non-technical resources for information about cryptocurrencies and blockchain

In case if you are interested in learning more about cryptocurrencies and blockchain, the following (recently published, non-technical) Motley Fool articles are quite helpful:

# Updating of the Finance 4335 Course Schedule to Accommodate today’s “Icepocalypse”

Since Baylor University is closed today as a result of today’s “Icepocalypse”, I have updated the Spring 2018 Finance 4335 Course Schedule accordingly. The net effect of today’s class cancellation is that the schedule for the remainder of the semester has been shifted forward; consequently, Problem Set 1 is now due on Thursday, January 18 (instead of today), and the two midterm exams will now take place on Thursday, February 15 and Tuesday, April 3 (instead of 2/13 and 3/29). Thursday’s class will begin with a quiz based upon the assigned readings for our statistics tutorial. The readings, problem sets, and lecture notes pages have also been updated to reflect the fact that Finance 4335 is now officially scheduled to meet 29 rather than 30 times during the Spring 2018 semester.

# Rules for calculating (math) derivatives

Here’s a particularly useful list of rules for calculating (math) derivatives (taken from the “Optimization” reading assignment):

# Problem Set 1 hint…

Problem Set 1 is due at the beginning of class on Tuesday, January 16. Here is a hint for solving the 4th question on problem set 1.

The objective is to determine how big a hospital must be so that the *cost per patient-day* is minimized. We are not interested in minimizing total cost; if this were the case, there would be no hospital because marginal costs are positive, which implies that total cost is positively related to the number of patient-days.

The cost equation *C* = 4,700,000 + 0.00013*X*^{2} tells you the total cost as a function of the number of patient-days. This is why you are asked in part “a” of the 4th question to derive a formula for the relationship between cost per patient-day and the number of patient days. Once you have that equation, then that is what you minimize, and you’ll be able to answer the question concerning optimal hospital size.
