Helium Miners

Helium just became something the IoT community preferred to trade. And at $9.00, you bet they trade it like crazy. I like that about the community. It's still not ridiculously overpriced, either.
Those DePin projects are for radio and communications nerds.
I know a guy who operates over 100 miners.
He's still making thousands of dollars a month, but he also has to run tech support for his own network. If a unit goes down, he has to troubleshoot it. He leased them, or put them in businesses and made his own network. Even at the $5.00 range, he was making enough to mine as a full-time living, but he wasn't getting filthy rich from it.
You can imagine a good miner making 10 or 12 HNT a month, and an average one getting 6 or 8. --- In the beginning, I could mine 50 to 100 in a week there for a while. Some weeks more as more miners went online.

Imagine you're a gas station owner and you want a little online portal where you can see all of your cooler's temperatures.
There are all kinds of relevant applications, but I'm not a computer science dude with a sales pitch.
He'd set up his miner and sensor cluster, toss them a contract with a little monthly sub.
