> Crypto currency? Seriously, that was their first thought? I find it hard to believe. It sounds like something a journalist would come up with to make a story more interesting. Uh, you assumed that it's the mainstream ones like Bitcoin or Ethereum but there is a reasonable suspicion that it's a Helium node (https://www.helium.com https://www.helium.com). According to what I've learned last year their shtick is that deploying on places that have less physical Helium nodes allows you to collect more HNT tokens which you can allegedly convert into cash while Helium will sell bandwidth à la Sigfox (https://www.sigfox.com/ https://www.sigfox.com/). In this particular case (unauthorized placement plus the particular spacing) this theory is more likely than an ADB-S collector (you only need a single unit to collect all data for miles) or privately-deployed seismographs.
