Few currencies can boast an 8,000-percent increase in value in just a few years, but the digital currency Bitcoin is different. Economists have compared the introduction of bitcoin to the gold rush in the late nineteenth century. There are now bitcoin millionaires who have become very rich from investing and trading in the e-currency.

And in Sweden, there are plenty of bitcoin enthusiasts, too. One of them is David Hedqvist, who founded the website, dedicated to stories about the world's fastest growing currency.

Bitcoins can be used to pay for anything from gadgets to food from anywhere in the world with the help of your phone or computer, so long as both parties accept the currency.
