# Modules Money with real backing and assets with real value come first; speculation, crypto and fraud come last. Every module has three levels: child, teenager, adult. Where a module describes laws, it gives the EU rule, an example from Bulgaria and what to check in your own country. The English version grows module by module — 28 of 30 are ready; all 30 are [in Bulgarian](https://pecuvo.eu/moduli/).
