The banking system and payment system in Iceland did not even shut down for a single minute during the collapse.
The Cyprian banking system and payment system has been shut down for a week.
Iceland is a small (only 320,000 people) homogenous island nation where family values are prime, one of the most friendliest and peaceful nations on Earth. The protests that followed were the most violent in our history, and more reminiscent of a revolution.
People tried to storm the parliament, threw rocks at the police (unthinkable act before the collapse), tried to attack the prime minister and parliamentary members.
How I experienced it:
If SHTF in Cyprus, beware, social unrest will follow. It may be a mix between Iceland style crash and Argentinian style crash.
