SBF did have a very unusual discounting policy, namely "no discounting", in fairness. I'm not aware of anyone other than SBF who bites the "keep double-or-nothing a 51% probability gamble forever, for infinite expected utility and probability 1 of going bust" bullet in favour of keeping going forever. (SBF espoused this policy in March 2022, if I recall correctly, on Conversations with Tyler.)
