Could Greece bankruptcy fuel the next Bitcoin rush? The answer is no. Here is why:
1. People from other countries don't care about Greece bankruptcy that much. For them is just another news from far away.
2. It does not make people suddenly realise that something like bitcoin is here. People don't know about bitcoin.
3. Even if people knew what bitcoin is there is not enough of infrastructure to use bitcoin in normal life on everyday basis.
4. Bitcoin is still too volatile when one day you have 1 BTC and it cost $300 and next your bitcoin is only worth $225.
You have some fine points, but 4 is partially true. Bitcoin isn't that volatile at the moment. Take a look at the 6 month chart, we've only had 1 big decline in that time period.
Things are going to improve over time. I Greece goes bankrupt, I could see some wealthy individuals buying into Bitcoin. They do have to hear about it first and learn how it works and how to use it.
The peoples from neighboring countries may not care but the banking institutions of said countries sure will, as many of them are Greek creditors. Italy, France, germany also have economic problems and the market will start to ask questions - we're already seeing bond prices turn, with Germany leading the way. No one wants Greece to default as the repercussions are unknowable.
It won't make people realize overnight that bitcoin is the answer but when it comes to money being confiscated (by bail in, devaluation or 'policy'), I'll bet people learn quick. Doesn't have to be the greeks themselves, likely to be other EU members. I would say in the event of a Greek exit people won't be coming to bitcoin so they can do the groceries, they'll be looking to keep their wealth away from TPTB and store their value.
Volatility is a problem with Bitcoin but in a crisis its a problem with everything.
