How many billionaires (or even millionaires that you know) keep the fact close to their chest? There's probably a lot of quite rich people out there who are more than happy to let you think someone else is richer than them.
Keeps the vultures and losers away from them and lets them get on with enjoying life.
In fact I'm certain there's quite a few people to go to extensive lengths to stay OUT of lists like this.
EDIT: Oh and paper money does not count until you execute your trade. Just ask anyone who was "rich" before the crash.
I challenge you to give some examples of people who've got that rich (legally) yet kept it a secret.
The literal interpretation of the challenge is a paradox. The contradiction is that a secret is no longer a secret once revealed (hence my comment).
I don't think that is what you were trying to convey. You do raise a valid point, but without any supporting evidence, it is thoroughly unconvincing. The absence of X is not enough to conclude that X does not exist (especially when X is being purposefully hidden, as in this case).
NOTE: I am not disagreeing with you. I don't know whether or not secret rich people exist.
This is a cool achievement and if he's worth $2B then so be it.
Otherwise his liquidity must be non-existent.
