Well about buyback mobile ro. They were a small company dealing in recycled mobile phones. Seems they were acquired by etn, now their website redirects to electroneum. I’ve tried to figure out the link but only scratched the surface. They are involved with ticket machine or it was started by same guys. Integrating etn API into epos systems maybe. Interesting. Huh let me know if you dig deeper. 
Edit:
I posted about it a few times and made a topic just over a month ago. It might explain the high interest coming from there.
