price manipulation is rampant in new markets. Exchange centers control most of the cryptocurrency movements, thus making them have the desire to gain profits by indirectly manipulating crypto prices. One way is to increase the price written on the exchange so that traders can buy or sell their crypto. The impact of manipulation like this can be compounded if there are thousands of new players that are easily exploited. Plus, price manipulation can be difficult to prove and control in an unregulated market. Central Exchange also has one point of shortage.
