Perhaps profit is the wrong goal to seek. Disestablishment of the bank-led catastrophicly bad double-or bust economy whilst protecting transaction banking for all honest productives worldwide is closer to my reason for wanting bitcoin to go well.
It is interesting you happened to mention that. I just read an article this morning on the Greek banking situation, and how people were desperately trying to get their lives back in order, but the banking restrictions are so draconian as to keep people from even paying there every day bills. The thought that occurred to me whilst reading through the article was along the lines of how a sudden "mass-adoption of crypto-currencies" throughout Greece could almost instantly render the banking restrictions null and void. Plus, it has the potential to permanently end the bank's control over the Greek citizens.
