Great curation work, and I don't just say that because I got the top position in it. The 4th one also grabbed my attention. zCash is another up and coming crypto that will effectively implement real anonymous internet cash.

I also have posted a little ways down, in my feed, https://steemit.com/economics/@l0k1/when-shtf-what-criteria-determine-the-safest-places-to-be which discusses the implications of functional, and more widely distributed systems of cryptocurrency filling the gaps, in especially some parts of the world more than others, while the centralised, elite controlled monetary systems are in the inevitable collapses they intentionally cause.

The changes that will be wrought by the emergence of decentralised electronic monetary systems, will change the world, I am quite sure of it. Steem in fact is a case in point. It's not just about the money. It's about ideas as well. The systems of digital cryptographic tokens are more than just fancy mathematics. They are ways of securing human society. Money is just the start. We still have to even start to really dip our toes into insurance, lending, and elimination of the ability to gather information about people without alerting them to it (better still, make it nearly impossible). I have proposals languishing that I am sure will eventually become mainstream in the cryptocurrency community, about how to secure people against simple crimes like theft and extortion and even defending the whole society against small groups using these tactics. It has militia-based applications as well. My vision is not little. I have been working on all of these things for a long time, and I think that with the emergence of distributed discussion forums, finally I will be able to get the ears of the right people who will know exactly how to apply what I have figured out.

Great work, keep it up :)
