Particularly for cryptocurrencies whose market capitalizations are already in the billions of dollars such as Bitcoin and Ether, one would need a huge amount of money to transact enough units of such cryptocurrencies just to be able to influence or manipulate their prices. When you take a look at Bitcoin, for example, whose average market capitalization hovers somewhere around US$50 billion, one would need at least US$10 billion to play around just to be able to manipulate demand and supply. Even if you're talking about Ether, whose average market cap is much smaller at "only" around US$25 billion to US$30 billion, one would still need a couple of billion dollar worth of transactions just to sway prices to his or her favor.
