7 days until the Euro crashes. Can't wait.
I'm assuming you are referring to the troika's demand that Greece submit a bail-out plan that they will not submit, prompting a Greek Gov't shutdown and a massive bank-run.
If this plays out as expected, the Euro will lose value against the GBP, Swiss Franc and USD, but that doesn't necessarily mean it will crash. What it will mean for bitcoin prices is far from certain. I don't see the price appreciating significantly in US Dollars until it becomes more widely utilized as a means to evade capital controls.
Why isn't it being used this way yet??
Because capital controls haven't been implemented to any great degree yet.
I would say it's more volatility, lack of confidence in the tech, and lack of easy ways to move large chunks of fiat in and out of BTC without attracting attention from regulators.
