> just like Facebook bought WhatsApp with private stock with crazy valuations
FB bought Instagram April 9, 2012 with ~ 30% cash and 70% stock, and then IPO'd May 18, 2012. That's probably what you mean. FB bought WhatsApp Feb 19, 2014 with ~ 25% cash and 75% public stock that was roughly 2x the IPO price. The private valuation might be crazy, but it's increased with public trading, so I dunno.
