the Federal Reserve should not act to
impede development of digital currencies. The I.R.S. will now tax bitcoins as
property.f The German Finance Ministry specifically endorsed Bitcoin as
“a unit of account” and allows it to be
used for tax and trading purposes.
If bitcoins can be converted into dollars and euros, they can be converted
into rubles and renminbi regardless
of whether Russia’s or China’s central
The question is not whether Bitcoin
has value; it already does. The question
is whether the efficiencies of a cyber-currency like Bitcoin can be merged
with the certainties of an honest central bank. I believe they can and will. At
some point, a country will step forward
and offer its currency as the cyber-cur-rency of choice. Will bitdollars, biteuros, bityen, or bitminbi become the
new global reserve currency? The first
country to fully embrace what Bitcoin
offers will do its own economy and the
world a favor.

Weimar Germany showed, politicians
can manipulate their currencies during a crisis. Citizens of Zimbabwe and
Ecuador use U.S. dollars as their national currencies precisely to reign in
such irresponsible behavior.
The decentralized nature of Bitcoin also means that no central bank
can intervene to manipulate or stabilize its value when large demand fluctuations occur. Examiners for the U.S.
central bank, the Federal Reserve,
object to Bitcoin because this makes
it volatile and a risky store of value.
Bitcoins traded for approximately $1
in April 2011 but above $1,000 in November 2013. In February 2014, they
dipped below $550.d If Bitcoin had a
central bank, it could have stepped
in to buy or sell bitcoins as needed.
An honest central broker can calm a
panicked market. The failure of central banks to step in led to the great
depression of 1929. The success of
central banks stepping in avoided a
greater recession than that of 2008.
Volatility alone is not a reason a
commodity cannot function as currency, only a reason why risk averters avoid it. People use put and call
options as a medium of exchange, a
store of value, and a unit of account all
the time. The real question is whether
markets can hedge against volatility.
Fluctuations also fall as a technology
gains wider acceptance. The larger the
user base, the less any single user can
affect prices. Overstock.com limits
bitcoin risk by trading in and out of
Critics have raised two other objections. The first is that Bitcoin promotes
illegal activity. Every transaction is
public, but the buyers and sellers listed
are simply Bitcoin addresses. The FBI
recently shut down Silk Road, a popular market that accepted bitcoin, for
facilitating illegal drug sales and other
6 But this is guilt by
association. Note that the other preferred currency of criminals is cash.
Over time, law enforcement will use
the public record of bitcoin transactions to track down crooks in ways they
never could for dollar bills.
Critics also point to theft as a risk
for Bitcoin, highlighting Mt. Gox, a
bitcoin exchange, robbed of $350 mil-

11 This problem is not new. Jesse
James has just gone digital. Wikipe-
dia lists a history of bank robberies by
country. The biggest is nearly $1 bil-
lion. In just 10 hours last year, cyber
criminals stole $45 million in real cur-
rency from real banks.
7 As a startup,
PayPal experienced fraud rates more
than five times that of established
credit cards before developing robust
systems of control.

from the Mt. Gox robbery is that any-
one thought “Magic: The Gathering
Online eXchange”—a place launched
to trade game cards—was the best
place to store large sums of money.e
As I see it, Bitcoin faces only one
serious threat: concerted opposition
by the world’s central banks. On De-
cember 5, 2013, China’s central bank
banned trading in bitcoins or convert-
ing it to renminbi. The ban greatly re-
duced demand, cutting bitcoin prices
25% just that week. Prices recovered
a bit, but then Russia’s Central Bank
banned it on February 7, 2014, drop-
ping the price 10%. If no one could
move bitcoins into any other currency,
then the only economy bitcoins could
support would be an internally limited
bitcoin exchange. Such a market could
exist, but it would be tiny.
A ban by all major central banks,
however, seems highly unlikely. Recent
U.S. Senate hearings concluded that
