There was NEVER $30B found. Internet Myth. JPMC found ~$30B in commercial loans/MBS. That's not cash. So if your referring to the ~1% servicing they could receive from the $30B in commercial loans... that's ~$243M for JPM "to find" after related expenses. Not nothing, but certainly not a great deal to JPM.
JPM has done everything possible to scrub the remarks from J. Dimon and related articles from the 2015 internet references. I posted links to it before ( gone now) no surprise. There was never $30B found per se' People/Institutions/Govt. just don't leave $30B sitting around anywhere ever...
