Denmark, the little country that stayed out of the EURO

Denmark and the United Kingdom received opt-outs from the Maastricht Treaty and do not have to join the euro until they choose to do so; Sweden has not received an opt-out, yet refuses to join for now, as well. Two referendums have been held on the issue up to now, both of which failed:

•  Denmark - 53.2% against, turnout 87.6% on 28 September 2000
•  Sweden - 56.1% against, turnout 81.2% on 14 September 2003

Denmark has been able to reduce its unemployment rate, and to boost its CAB Current Account surplus. What did smart Denmark know that the other small countries did not foresee ? 
But no country is perfect! 
An alliance of right-wing parties won the Danish general election on 18-June-2015, in a close race with the dramatic rise of the   anti-immigration Danish People's Party (DPP). Coalition talks failed and  Denmark's new Liberal prime minister, Lars Løkke Rasmussen just took office with less than 20% of the popular vote.
