Why would anyone waste their money on Greeks anymore?
Bitcoin needs Greece, more than Greece needs Bitcoin.
Do you think that Greece will be an exception, and no other country is going to default on its debt? I don't think so. Several countries are going to follow the precedent set by Greece. And that is why Greece is important for us. If we can prove that Bitcoin can be used to help the Greeks, then imagine the acceptability we will get by the time of the second crisis.
No in the current state. The network is struggling with an ongoing attack, bring the Greek population in and we'll have some serious problems.
We need to fix the scalability problem before thinking about any of this, then we'll be ready.
Remember that BTC can only cope with 7 tx per second which is ridiculous to deal with a real economy.
