Once upon a time there were three people in Arnhem who wanted to pay their drinks with Bitcoin. They contacted different companies in their city, to convince them to accept payments in Bitcoin.
On May 28 2014, they officially opened their Bitcoin City and at that time 15 merchants already accepted the currency. Soon after, many more followed. At this moment there are more than 100 companies accepting Bitcoin for payment.
The city attracts many tourists who want to spend an entire weekend, paying in Bitcoin only. They stay in one of the hotels or B&Bs which support payments in the digital currency.
May 28 is the birthday of Arnhem Bitcoin City and they celebrate that every year. This year it's the third birthday. If you happen to be in the neighbourhood, pay a visit.
