Lets remember that Satoshi Nakamoto's purpose when he was created Bitcoin is to eliminate the middleman or the Centralized aspect of the present "Financial Structure" but in reality Blockchain Technology is not fully utilized as of Today. the main reason why Blockchain is famous now because of the Cryptocurrency I believe that in the near future Blockchain Technology will fully utilized and used in real life aspect such as medical and Health,Transportation,Banking and Finance,Education etc. this is the begining of the Decentralized era thanks to Blockchain and Satoshi Nakamoto.
