It is a little late to tell my opinion because things are more cleared now but I don't think that Greeks will buy bitcoins. First because the common people don't have money, second because they need money to spend in everyday things (so no possibility to save), and third because now they have signed the agreement of the help with the European Countries.
i hear everywhere that whales are accumulating coins, but they already had plenty of time to do so. i think it's more due to the fact that traders overal aren't ready for a price jump.
