Decred is similar to normal money. It’s a currency. The big difference: Decred is designed to be completely autonomous, open source, and driven by the community. No central banks needed.
Decred is similar to Bitcoin. There will only be 21M coins created, ever. The big difference: Decred uses advanced and innovative technology that solves blockchain governance. No hard forks needed. Exchanges will never have to deal with customer requests for splits. The general public will never have to sift through contentious forks or be fooled by claims of a "better Decred".
The Decred project was created in the spirit of open participation. Everyone can join and contribute. All stakeholders of Decred can decide to take part in the decision-making process. The project is constantly evolving, so you can expect more innovations in the future.
