Ah, gotcha. Well, nobody seems to think that Britain will be a runaway export success on account of leaving the EU - most "for" seem to think it will "be ok." Shortly after May invokes and shortly after separation is done there will probably be very large dips in GBP. That info would be much more useful if anything at all were clear about what Trump would do to the dollar in the meantime (so far it's a stock market party, though) - if those are good entry points for you on GBP, you might do it then. If you're fine holding US investments in the meantime, that's what I would do, but it's less liquid if something could make you want to move more quickly (I'm not sure what governs your time horizon, but that's the only advantage to having it in the other currency early).
