Unlike stock or commodity transactions, the value of Bitcoin is unpredictable. Values ​​can go up and down in one trading day only

However, there is an indication of the value manipulation of Bitcoin. This manipulation occurred in the year 2013 ago.

At that time, the price of Bitcoin could rise from US $ 150 / coin to US $ 1,000 / coin. This increase only occurs in a vulnerable time of only two months.

There are four researchers who found manipulation. According to them a surge in the value of Bitcoin is done by one person.

In his paper entitled "Price Manipulation in a Bitcoin Ecosystem" published in the journal Monetary Economics, Neil Gandal, JT Hamrick, Tyler Moore and Tali Oberman describe suspicious activity at the digital currency exchange center (cryptocurrency), Mt. Gox, which affects the value of Bitcoin Cs in 2013.

As quoted by TechCrunch and quoted CNBC, the researchers found price manipulation done two bots and listed as "??" in the user's country. They named this bot "Mark" and "Willy".

Markus buys and sells bitcoins at random prices and does not pay transaction fees. Upon further inspection, Mark actually did not pay to receive Bitcoin. Mark generates 335,889 bitcoins and is active from 14 February 2013 to 27 September 2013.

Seven hours after Mark becomes inactive, Willy appears with 49 accounts. Each of these Willy accounts sequentially purchases bitcoins worth US $ 2.5 million and then becomes inactive. During this period, bitcoin prices soared.
