How we work
Universe of Crypto is a plain-language education project from Interadtive Media LLC, in early development. These are the working rules for guides once they are published.
Each guide will end with the list of sources behind its statements.
Opinion and open debates are marked as interpretation, separate from stated fact.
Guides will be drafted with AI assistance and will say so on the page.
Every guide will link to the corrections policy. Educational only; not investment, legal or tax advice.
