What would it take to make $72M?

If you start with $1000 and make a profit of 6% per day for a full year, you're there. Or start with $100 and make 7% per day. But if you can only generate a piddly 1% per day (which itself would be a mind-blowing achievement for any fund manager), you'll need $10M to start.

The article is very, very short on details of what has actually happened here, apart from "Rich people like to hang out with other rich people."
