Me too. People posting the live USD/GBP rate are going to end up looking as daft as everyone pointing at the FTSE 100 the week after the referendum.
Part of the reason it's difficult to be positive about Brexit, for me, is that I can barely listen to a Brexit supporter for a minute without them saying something that implies a severe lack of understanding. Your comment here, for example...
Since the referendum, the rise/fall of the FTSE 100 has been largely governed by the rise/fall in the pound. One (the pound) is dictating the other (the FTSE 100). The pound has dropped because of Brexit and there is -no evidence whatsoever- that it's going to go back to anywhere near where it was back before the vote. It's lost a significant proportion of the gains from yesterday already, and we're not far off where we were at the beginning of this week.
The fall of the GBP has been -the- economic story of the last few months in this country. The rise of the FTSE was a consequence of the fall in GBP. Read the FTSE value in dollars, (or euros, if you wish), rather than pounds, and you realise that people talking up the rise in the FTSE were either deeply misled or trying to mislead. Noting the fall in the pound, and worrying about the consequences, is, on the contrary, deeply reasonable.
This is my problem. I have long accepted that Brexit is going to happen, and that it's going to be a hard Brexit. I want to believe that it's not going to be a disaster for my country. I'd like, therefore, to hear sensible statements from those responsible for this situation. I want to hear sensible statements from the Conservative government, but they increasingly sound like UKIP did a few months ago. I want to hear sensible statements from Brexit voters and supporters, but I continue to hear the same tripe I was hearing before and immediately after the referendum. I want to be positive about this country's future: I am not.
