If Greeks are really trying to save their spending power, a dollar linked currency makes the most sense.
Actually that is their problem the link to the euro (which is similar to the dollar in therm of printing policy...)
They cant devalue their money because they have no admin rights on the euro central bank.
Devaluating is a key in modern economics if you like it or not its a practise.
The US and EU do it, and others.
It is used to balance the econmy demand and supply for the money (economy exports, growth and others).
The problem of Greece is their economy deviates a lot from the EU-leader Germany, which generates a gap
that could be fixed by devaluating the money. But like i said, they cant because they have no own currency.

This is assuming it is even a Greek buy-in. I haven't looked into it and I haven't read anything to confirm deny the speculation, but it makes sense on the surface.
If I'm worried that my money will be seized or devalued tomorrow, I'm not worrying about the broader political or economic implications; I am only looking to secure my spending power for the near term in hopes that it maintains its current value for the foreseeable future or until a better option shows itself or is created.
Bitcoin doesn't do this (volatile, at least historically so), but a cryptocurrency tethered to the US dollar does--I'd assume Greeks wouldn't be interested in a Euro tethered coin at the moment.
Even better would be a cryptocurrency tied to commodities (food, energy) and the housing market where you are guaranteed to keep your purchasing power without losing sleep over the potential of political mismanagement.
When you want to keep your purchasing power stable its a problem.
Because it depends mainly on the period you withdraw you money for spending.
You can hedge your savings in the Forex market between the major currencies
(Eur/USD buy & sell at same price) and if you like also AUD Yen , Gold etc.
Keep in mind that there are conversion or trading expenses, and most important you cant
pay with gold or foreign money at your country. (Bills,Food,rent,gasoline)
So for me the only soloution is, to earn money faster than the inflation boils me ;-)
Easier said than done, but doing nothing is worse.
So for me i learned to trade forex(daytrading), and crypto (longterm).
There are also other ways, like you can buy a house and offer the rooms for rent.
Trade stuff like cars/art, whatever you are familiar with.
The trick is, try to gain passive income too your active work.
Another important thing is keep the value of your expenses under your income, so you can save for the hard times.
