Since the start of the year, the Japanese yen has risen by about 12 percent against the dollar. The euro has fallen by about 1 percent.
Then there's bitcoin, a virtual currency that doesn't even exist in the physical world. In the past few months, the value of bitcoin has risen by more than 1,000 percent — from less than $20 per bitcoin a few months ago to more than $200 today.

Bitcoin, the digital currency that trades outside the control of central banks and international borders, reached new heights Tuesday, surpassing the $200 mark for the first time. That level comes just five days after bitcoin approached $150, a development that Mt.Gox, the largest exchange service for the currency, deemed to be "epic."
Bitcoin's rise has been sharp. It was only two months ago that exchange rates put a single bitcoin's value at around $20.
University of Louisville fans have had a lot to cheer about lately — and not just basketball.
Monday's big victory by Louisville's men's basketball team over Michigan is just the latest success for the school and for an athletic department that is quickly becoming one of the country's most admired.
In January, the football team upset fourth-ranked Florida to win the Sugar Bowl, and coach Charlie Strong turned down a lucrative offer from the University of Tennessee to continue rebuilding the Louisville program.
Republicans don't often make high-profile speeches at Howard University, one of the country's most prominent historically black schools. But on Wednesday, Kentucky Sen. Rand Paul will talk to Howard students about how his party can be more inclusive.
Paul believes one answer is libertarianism — and party leaders are starting to think he might be on to something.
