Despite the fact that bitcoin was the first currency to introduce the blockchain to the world, the blockchain may well exist without it. If one page on the Internet "will fall", the Internet will not cease to exist. Most people have never seen the first website created. It was a clean white page called the World Wide Web with a list of text links. No one could imagine that this completely nondescript page will turn our world into the one we see today. Improved and faster versions of blockchain are already coming to this world, making improvements to the original bitcoin, flowing into separate cryptocurrencies like Ethereum and Ripple. The market already has a lot of cryptocurrencies, which are based on constantly improving blockchain technology.
