The UK economy is not that far behind the USA on long term growth & everyone in the EU still wants to live here - I think GBP is cheap because of political uncertainty over BREXIT (That will go on for a few years yet). I'm no great forex trader but I do follow the trend and price of GBP/USD it went as low as 1.13, I wish I had the short term answer, we would be forex Billionaires tomorrow like George Soros 🤑😄
