He's a smart charming hardworking entrepreneur expert at marketing who is eager to take risks (which is such a 'type' https://gwern.net/doc/psychiatry/bipolar/energy/index that you should already be thinking 'bipolar?'); but he is not gaslighting people to deny his scams or immune to shame and feels bad about the fraud & scamming people, so it's not narcissism or psychopathy.
The rather pointed but otherwise unexplained mentions of his lack of showering & smelling is a dogwhistle: the smelling is from the manic cycles where he stops bothering with such wastes of time meant for the little people; other manic cycle symptoms like sleeplessness would generally go unnoticed in the normal frenetic lifestyle of a up-all-night nightlife promoter (which of course is a great way to get the sleeplessness that would often trigger a manic cycle in the first place). And then when he disappears for a while or ghosts people, those are the depressive cycles.
