How do you develop a minimal chain scheme for increasing trust? As in, do you first get people to your website and then ask them to contribute in decentralization by downloading the chain? Bitcoin cannot work without people noticing and liking Bitcoin. If it didn't get traction, it'd still be centralized haha - only one entity would have the whole chain.
