Does that sound like anything more than routine common sense no matter where you're travelling to?
This is common sense wherever and whenever you travel. Banking networks fail (although more frequently in developing countries), credit/debit cards get hacked, cash gets stolen. Having multiple forms of payment carried in multiple places will be your friend. I have bailed out colleagues more than once when their credit/debit card didn't work. While I am not anticipating an untimely Grexit, these precautions would serve you well in that circumstance.
Another thing to keep in mind when carrying cashe of significant amounts is to be aware of currency restrictions of your destination country. In the event of a financial crisis in your destination country, make sure those restrictions have not changed.
