I think we need bitcoin to usher ina new era of finance and money in general. Bitcoin goes back to the early days of exchange of value wherein the two parties invlolved are the one's responsible for their transaction just like in barter. Remember barter is the exchange of goods and services as per your agreement. Then came in metals, precious metals, nuggets, coin, stamped coins which changed the world back then. After that came paper money backed by gold and silver, which was outdated by the free flowing model wherein the paper is just based on trust on the sovereign country of issuer, basically an i owe you. Then it is computerized for efficiency and record keeping. Now, money is evolving and bitcoin sets that pace. Best of all that came, peer to peer, no intermediaries, and no control by banks or govt but fees for miners for keeping the system running, and fast as compared to money transfers locally and internationally.
