In the 27th and 30th August 2013 Markus bought a lot of BTC, further faking the bull market (total net BTC bought by Markus = 297628). From the Willy report:

In this table, the first two trades (buy/sell pairs) are by some regular user with ID 238168. In the second trade, this user buys 0.398 BTC for $15.13. The next trade is some large market buy by Markus (ID 698630): note how the “$15.13″ value from the previous trade seems to “stick”; regardless of the volume of BTC bought, the value paid is always $15.13. This is speculation, but perhaps for Markus, the “Money” spent field is in fact empty, and the program that generates the trading logs simply takes whatever value was already there before. In other words, Markus is somehow buying tons of BTC without spending a dime.
