Fake volume is for building coins and exchanges up to rank on CMC, the manipulation of the price is mainly made in the leverage or margin trading exchanges, where people who don't necessarily own any of the Bitcoin they trade, do the futures trading and short or long the market as a price prediction. That, for me is where the big manipulation is. Bitcoin being so scarce should by now be worth a lot more, but since futures trading was introduced, that is what killed the price of Bitcoin, not the wash trading that is occurring on the exchanges so they can rank higher on Coinmarketcap. We need to be discerning where we want to trade and also what pairings, we need good liquidity in the market but we can eventually get that when the market cap is far bigger, like there is in FX trading.
