Re the 'worse case scenario', of course we would want the best deal possible, and remember the UK is also a significant export market for the EU. My inference is that in negotiating, anything better than base WTO terms is a bonus. It's also in everyone's interest that currency conversions remain as stable as possible. The Euro's future only offers more uncertainty.
EU citizens would not have free movement, but wouldn't be precluded from employment wither. They would have to qualify for employment the same as any non EU citizen does at the moment.
My reference to Soros was in the context of global currency 'players', and not to him personally.
