As a (former) software dev, I can understand wanting to be paid for your time and efforts. Really.

But I feel like LoRa Mesh networking is a community of people who don’t like or trust traditional infrastructures. Getting those two things aligned might be hard. Good luck.

Just as a side note, I remember Threema having an option to pay with shitcoin, and then mail you an anonymous activation code. I understand that this is way harder to implement properly, but it might get you more acceptance.
