Dear Fakhoury, a word of advise:
Thousands of Greeks lost their savings, after the 2012 PSI haircut, which included their "super-duper-guaranteed " government-issued bonds.
There is no such thing as "100% Guaranteed", when banks and governments are involved.
Just HODL!

Unfortunately Greeks recent history is not positive in terms of managing their national debt. It was not surprising that government reached out for money of their citizens to help itself.
If you are living in any country with similar problems and suspect that your national currency is not so stable, don't invest in it and don't keep it!
Also history of Cyprus and Greek show, that your money stored in banks are no longer fully yours...
