I hear ya brother and I have made alotta bucks through my drip investments.
However, I am at a point where I can get by without the income so I like to live a bit more dangerously in the technical world and trade shorter term swings(casino rush I guess, lol).
I am, however, looking at NBG in a longer term light. Trading ADR's is more difficult in a short term environment.
My worry with Greece is that for many, many years they have created a culture dependent on the country to give them early retirement at great rates and paying for it with debt, through their socialist style of govt.
As came to roost recently, it's not sustainable.
Now they are standing in line with their hand out to Eurozone's flourishing countries.
I don't think they can ever get back to the lofty heights of yesteryear unless they can come up with real products that the world wants/needs and they can tighten up dramatically on the governmental policies that got them here in the first place, and that takes a reversal in culture(very slow in coming and hard to do).
I think it is doable, but will take many, many years.
A bright spot in Greece is the many shipping companies based there, which I believe are on the cusp of a return to profitability and will bounce back in a much more reasonable time frame then the banking system.
Just my two cents. IMHO
