Most of them aren't so stupid as to put all their eggs in one basket. Usually VC is done by very wealthy individuals or institutions which place bets on dozens or even hundreds of startups in the hope that one will become the next google. Additionally, one doesn't need to hold out until the startup makes money, only until it gets acquired by another company.
