Few notes- as with Bitcoin, it's too late to get it when it's wrecked, with Reticulum and Cashu, it is much better to build the network and the mints while internet and more importantly shipping still works. You will need long range radios, antennas, experience and especially community.

With Ham radio - it is a great community, you'll learn a lot, but there's a philosophical divide. Ham operators often don't like encryption, ham is based on complete openness and everyone listening. Reticulum is cypherpunk and encrypted. Not only by default, encryption is essential building block and Reticulum does not work without it. In many countries, encrypted radio communication on the "free" (not requiring license) bands is often limited. I'm not saying don't do Ham, on the contrary, you'll learn a lot, but expect some resistance with cypherpunk tech.
