Never played with this roulette, but someone mentioned nice comparison:
Facebook buying Instagram, without info how much was cash. 80bil is a bubble, so shaving 1/80th of it for an app that fixes their shortcommings is a steal (if the buyout was in stock as all assume). Once **** hits the fan how much actual property can FB offer while bankrupting? 1/100 of this? Nokia can cover all their shareholders just by selling their HW/real estate/IP... Go buy FB stock, it is risk free
