Bitcoin has been impressive in a lot of ways since it's beginning but the one thing that blew me out the most was the ideology. A foolproof peer to peer online transaction system based on blockchain technology was just a beautiful set of works executed and implemented by Satoshi and no wonder it has already made its mark in every field it is being used in.
I believe we all agree that bitcoin is really a big help when it comes efficiency and cashless transactions. These are just part or features of having a blockchain process and technology which I am truly impressed.
