I still don't think brexit is having any effect on bitcoi. Price is still around about what it was before brexi, maybe even lower. For people to use bitcoin to invest in they need to know about it and feel that its a safe be. And at the momenti just don't think with people are aware of bitcoin.
price will always start changing as soon as there is a news not after everything is done and dusted. and in this case the $100+ rise was started as soon as brexit news was released and there was a small speculation about bitcoin price. after price hit bitcointalk and everybody was talking about it, it was already too late and price has gone up already.
besides in my opinion the biggest effect that brextit had on bitcoin was the good news that is being spread about bitcoin because of it. and that is better than any price rise.
