But none of those had revenues of even 10 billion even at their height of success. FB does more than that every quarter, on track to do 55 billion in 2018. Cash warchest of $41 billion with ZERO debt. They keep crushing any new competition that pops up. Just ask Snapchat, their valuation went from $25 billion to 8 in less than a year. FB tried to buy them, they declined so Zuck just copied what they have on Insta and now Snap is losing users(down to 180 million) while Insta is gaining them(500 million). So you can wager whatever you want, its your money but I'd advise waging it against FB. They will buy the new competition, if they decline, he'll just copy it. And given the new regulations that are to descend upon them via congress its going to make it even more difficult for any new competition. FB will just track along and make them even more entrenched given their ridiculous revenues and margins.
