I think about 10-15M. It allows you to have all the nice things that are fun to have: sports car, boat, nice house, lots of travelling and etc. At the same time it's not the amount where things get complicated very quickly. Sure, having 500M is nice but then it also becomes a hassle on its own on how to retain it and etc.
