The entire btc marketcap is multiple times lower than some random mobile messaging application for smartphones that is priced in the range of ...billions. And Bitcoin represents a financial revolution as both money (total money supply = tens of trillions in marketcap) and a player in the money-transfer market (trillions in marketcap with banks, swift, credit cards).
As for the manipulation, it's unlikely big BTC whales want to hold the price down (or induce it to an artificially higher level).
-Price suppression would cost them their BTCs (dumping to lower the price)
-A price bubble would cost them a lot of fiat to sustain, to absorb daily coin production.
The fiat Elite have more to gain by manipulating BTC.
