Excuse me if this question is naive, but with such a small market what prevents someone from buying 10k worth of bitcoin, letting that be a view-able trade causing the price to increase, then dumping it when the market goes up a bit? Rinse and repeat you are manipulating the market with a large amount of cash and making a ton of money.
What other market manipulation tactics are we susceptible to with such a small market? What kind of voluntary oversight can we enact to discourage these tactics?
What's to say that the market will go up after you buy a large order?
