Brexit will make Bitcoin more popular
I think the media and press coverage Bitcoin is getting as being a safe-haven asset will increase investor awareness and eventually make it a recognized safe-haven asset as investors reevaluate options. But I expect that to occur over a more gradual timespan of months to years as investors encounter long-term global financial instability. Very few people had their finger on a trigger to buy BTC the way traders were ready to shift GDP to USD or gold.
Until Bitcoin has an ETF or Forex presence (on major Forex brokers) I don't expect markets to react on a similar timescale.
