Visiting Yulai, I had the opportunity to speak to KIAEddz, CEO of mercenary corporation KIA Corp (KillerZ in Action). Asking him why he thought most trade was leaving Yulai, he responded:
"Two words. It's dead. It's simply too many jumps, too far away."
And he has a point. It seems Oursulaert and Jita have replaced Yulai, probably because of their location. Another factor, according to KIAEddz, is the presence of high-profile employers, who are eager to employ privateer pod-pilots. Oursulaert alone boasts the highest number of registered pod-pilots, whereas Yulai numbers have dropped staggeringly. To compare - at the time this article was printed, Oursulaert had 232 active pilots, Yulai had only 48. Jita numbered 208 pilots in space.
Although the Yulai torch seems to have passed to Caldari space, each region seems to have its own hotspot. Condensed information gathered by influential traders shows that Rens, Pator, Amarr and Alenia have all benefitted from the proactive anti-smuggling stances of the Minmatar Republic and Gallente Federation.
