Tomorrow Catalonia will try to vote for independence, and Spain will try to stop them (looks like they might get violent).
IF the Catalans vote to leave and declare independence, then all hell will break loose, and we might see a flight to safety towards bitcoin. It depends entirely on how ugly it gets.
This could be possible... But i don't think that political instability alone is enough to make people flood in bitcoin.
However as i've said, when financial situations get real bad, so bad that people cannot transact on a daily basis for their basic needs since their national currency is in a hyperinflationary mess, they will look for an alternative.
An alternative that is a store of value. So it's really only either bitcoin or preciosu metals. Bitcoin is gaining popularity as a safe haven like this.
