US Couple Boldly Travels the World Using Only Bitcoin

Austin and Beccy Craig, a couple from the United States, traveled around America, Europe, and Asia for 100 days using only Bitcoin as a payment method in 2013. The funds were used for entertainment, grocery shopping, gasoline, rent, and insurance.
Despite this, the couple from Utah still keeps a certain amount of cash as an emergency reserve, for instance for medical needs. The couple is determined to only use goods and services that can be purchased with Bitcoin, including for their mobile phone.
Their goal is not only to understand Bitcoin technology, but also to educate the public. They successfully raised over US$70,000 through Kickstarter, plus direct donations in the form of cryptocurrency and sponsorships.
"The goal is to understand how the Bitcoin ecosystem has developed, what needs to be changed, and how easy it is to use, understand, and explain it," said Austin, as quoted by Forbes.
They started with a small Bitcoin deposit and plan to persuade their boss to pay them in Bitcoin, because the funds from Kickstarter are only used for the documentary film production, not living expenses. Fortunately, their boss is open to the idea.
Both had difficulty finding homeowners and shops willing to accept Bitcoin, but in the end, Craig convinced the stores to accept Bitcoin by offering technical assistance or paying a higher price. They even went without food for 24 hours because of this.
Interestingly, the story of the couple was documented in a film titled "Life on Bitcoin" and garnered attention from major media outlets such as Forbes and Bloomberg.
