Holstein became known as The Bolito King and went on to amass a vast fortune through the numbers game. But he was not selfish with his wealth. He became a humanitarian and philanthropist, building dormitories at black colleges, donating money to black causes, supporting a Baptist school in Liberia and many of Harlems poor children, contributing to black artists, publications and numerous charities, establishing hurricane relief funds for the Virgin Islands and founding a museum. Casper Holsteins wealth was estimated to be at least well over $2 million, from having operated a numbers game. Some say his income averaged almost $12,000 a day. Redding, in his Playing the Numbers, says about Holstein, In a year he owned three of the finest apartment buildings in Harlem, a fleet of expensive cars, a home on Long Island, and several thousand acres of farmland in Virginia. It did not take long for Casper Holsteins success to take a strange turn.
