I don't see what Brexit has got to do with Bitcoin. Unless you think that it will accelerate the death of the Euro and the EU asset strippers. The UK will be immensely stronger once it has regained its independence and self-determination. It is likely that the bankers will create their own replacement for the Euro, and reluctance to accept that could boost Bitcoin.
They will not be stronger. Businesses are already suffering from different problems , one of which is lack of good workforce.
Those foreigners which some Brits hate so much are going elsewhere like Germany. But wait, who will work in their fields when all the foreigners are gone? no one because most British people do not want the dirty jobs!
EU gives enormous economical benefits for those who participate in the Union. British are already searching for other unions which are the same as European union only with less benefits and less responsibilities. Noone likes to sit in customs , no business likes customs and taxes!
BTW . Check the BTC chart date when british voted for leaving, Bitcoin had huge gains. There is a possibility that part of GBP will exit to BTC again.
