YUCJ [Yu Coin] Token
About YUCJ

Website
Yu Coin is a decentralized, blockchain-powered universal digital currency that aims to usher in the era of using cryptocurrency in financial transactions and certifications in the jade industry instead of cash and paper certification. The concept of using cryptocurrency as a currency has already been known to mankind for years now and the priceless idea is as old as money itself. This familiarity, combined with its amusing concept of digital certification with non-fungible tokens, gives Yu Coin a unique advantage and greater chance of mass adoption despite being new in the cryptocurrency space. At its core, Yu Coin allows people to make financial transactions such as payments and fund transfers without going through a trusted third party or middle man.
