the timeline of PV's first comment on the Sulja web forum that Wessal obtained 100 mil (as so he believed) to your response of PV's reasoning of why Wessal sold off their shares leaves a very small window of execution.. one would question this timeline allowing Wessal to exit just in time for the so timely news slashing..
You asked:
Why Wessal has sold out their shares(assuming they exist and they had some shares)
Answer:
Wessal didn't like the publicity they were getting from the media. In fact, most middle east companies do not appreciate the publicity. In addition, Wessal didn't act as they were expected once the publicity hit in full force and Petar said he was somewhat relieved they were out. However, he continues to have a relationship with them through his company, Kore, which benefits Sulja, since Sulja supplies Kore.
