Every cryptocurrency project sets out its aims and objectives in a whitepaper that contains the project abstract as well as all the useful information about how it works and what it will achieve. DogeMiyagi's (MIYAGI) whitepaper is full of information that is easily accessible for anyone to understand, while Ethereum (ETH) and Bitcoin (BTC) keep their whitepapers as a reference to their original vision, although the currencies have changed significantly since they were initially created.
