Assuming that the devious genie made this offer to start on Feb 1st in a non-leap year, I’d go for the $100,000/day

Even if it was to be a 31 day month, $31 million is quite enough for me, and genies are notoriously unreliable, so I’d go for the $100,000/day because it pays more right up to day 28.

How are you getting 31 million?

I made a slight error there :)
Should be $3.1 million of course, which is hardly enough for a decent house these days.
Have to think about it :)
