Traveling with cryptocurrency

I'm sure that I am not the first to come up with this, but travelling with money is a serious liability. 

if the amount of money is $10,000 or more, including mailing money into or out of the country, you must first report it on the correct Currency Reporting Form to the U.S. Customs agency. Failure to report money is a violation of the U.S. Currency and Foreign Transaction Reporting Act. 

... and no more foreign transaction fees.

 A foreign transaction fee, sometimes referred to as an FX fee, is a surcharge on your bill that appears when you make a purchase that passes through a foreign bank, or is in a currency other than the U.S. dollar (USD). The most common FX fee that credit card issuers tack onto your bill is around 3%. 

Yay, now I want to go travel! I heard Asia loves bitcoin
