Every time the possibility of mass adoption is mentioned there's always a govt official or media outlet saying "see, it's not secure you could lose your investment"... this is why the majority of VC funding needs to belong to improving security first. Until we can go several months without more news about exchanges getting hacked or several people hitting the forums with new lost coins it will be a tough sell.
It doesn't matter that the banks are also being hacked and major retailers CC systems are being compromised... that info isn't going to change the masses way of doing business as usual... we have to prove without a doubt that the wallet system is far more secure.
Sure best practices can prevent theft but for some reason it's not sinking in.
Let the traditional old heads have their regulated exchanges if that makes them feel safe as long as this isn't forced on those that don't want to be controlled/manipulated.

A mass campaign for supporting greece and bitcoin adaption could be a good start.

Picturing a massive letter drop from the sky 

greekcoin would be a bad idea because it could easily crash due to shaky sentiment and people trading out of it. 

why not just use Bitcoin?  it's way more established, and I don't see any reason to believe some alt coin would gain more users faster.

Well, this is very bold statement, but I don't agree.
Greece can't be saved by bitcoin.
They need to recover economy and find new jobs for their people.
What is the point in changing currency if people don't work?
If people can work and national economy become better, nobody will care much in what currency is their salary.

Bitcoin puts them on a level playing field with USD… Bitcoin is essentially adopting all major fiat in one basket for now… They can have access to the global economy. Bitcoin is a boon to the economy. It opens up the economy, the rest is on the people of greece not the politicians. They can take their own future and wealth into their own hands. If they don't want to work, produce or educate themselves then, there is nothing we can do to help them, but bitcoin free's them from the debt systems, greeces systemic poor financial conditions are no longer the fault of the ECB essentially.

Nothing can save Greece.

They want to consume more than they produce, forever.

There's no way to make that happen anywhere in the world

Is there a better time for Andreas to visit Greece? {His country of origin, correct me if I am wrong?} They need the proper guidance to get out of this mess.

It's a pity hardware wallets like the Trezor is so expensive... It would be a great tool to help these people. {It will also solve the security concerns... I do not know of any hacking losses with a Trezor}

Companies like Coinbase BitPay should also aggresively reach out to these people, to bring solutions to the lack of merchants who accepts Bitcoin in Greece.

This is not going to play out very good to the average to poor people in Greece. 

Why Greece Should Not Switch To Bitcoin

In some discussions about Greece exiting the euro, it has been suggested that Greece should swap the euro for bitcoin. At first glance, bitcoin may appear to be the cure. But if the euro is the problem, switching to Bitcoin would be like trying to cure a headache with a bullet to the brain.
