Greece got themselves into this mess, and need to learn to take responsibility and fix their situation. Giving them bitcoin would not help them, only possibly delay the inevitable even more, plus they would most likely cash it all out and the fiat would disappear almost instantly. From what I have seen, a lot of people that get into debt and end up declaring bankruptcy to get a "clean slate/bailout" only end up going back into debt again and often end up in bankruptcy again.

IF Satoshi does still have access to most or all of these coins, with a purchasing power of $200-$1000 each, you have a lot of power you can use to make further changes to certain things in this word, like charities, research, science etc, but I would not want to donate or use these bitcoins until the ecosystem for bitcoin is finally established, so that those you send bitcoin to, continue to use it as bitcoin for purchases and expenses instead of cashing out.

Then like mentioned previously, if he ever got found out and it was confirmed he had a lot of coins still, he would be bombarded by beggars, scammers, threats etc. I for one hope he is never found, but still alive, and would like to see some of his coins used in the distant future for good.
