If, on the 1st of January 2016, the national currency of Greece is still the Euro, I will pay Alexander Biersack €3. Otherwise, Alexander will pay me €2.
The odds I've offered are as generous as they could have been given my low level of confidence :) I say this now and will not repeat it if and when I lose this bet, nor prior to it, especially if things are looking like I am going to lose.
