It's been quite the week over at Goldman Sachs. After a 28-year stint at the bank in various roles, Stephen Scherr will step down as chief financial officer, paving the way for the co-head of its global financing group, Denis Coleman to take over as CFO January. Once rejected from a job at the bank in his younger days, Coleman has ascended to one of the toughest jobs of all — continuing Goldman's expansion out of its Wall Street roots and into consumers' pockets.

One Goldman alum who struck gold in crypto also resurfaced this week. Aziz McMahon reportedly made millions trading dogecoin before his departure in May, he's now resurfaced at a healthcare company that claims to be working on a "cure to all pathogens known to mankind".
