He has 6.5 BILLIONS. That's almost double what Brian Chesky (CEO Airbnb) has including paper money, more than Evan (CEO Snapchat) has, and more than Travis (CEO Uber) has including the ridiculous valuation. Just an observation.
Similarly it's crazy to see how high up people like Moskovitz are in billionaire lists. I've gotten used to Facebook being a $400B company (now they are a $500B company), so obviously stock owners like Moskovitz will be worth tens of billions, but it's still crazy nonetheless. Just checked. He's ranked 60th richest.
I think WhatsApp was just overvalued, personally. It's excellent in many ways, but I cannot see Facebook ever making their money back on it.
