It doesn't have to be a new concept to be necessary. Why do people on hacker news constantly have to miss the point? Most ideas are revised versions of things that have been done for centuries. The cult of "new" is ridiculous.
it's in the title. "a NEW form of currency"
Exactly, you cant even read past the title to pull out the most important part (hint: the definition of the word "new" isnt the most critical thing to talk about)
Argue as you want, the title is wrong. This is a 1+1=2 forum.
