BTM,,,that's the safe bet,,,lol, however, you will leave alot of money on the table by the time a divvie happens.
I don't think the EU will let the Greek banks go under(let alone its money center bank), and that is why I dollar cost avg in and currently lower my cost basis avg with each purchase(currently).
I have an investment amount in mind where I will stop and I have quite a ways to go yet(will prob take me a few years to get there).
I expect by 2020 NBG will be trading much higher than it is today.
I hope I live long enough to see it,,,lol.
In any event, my daughter will get the scraps,,,lol.
