Bitcoin will change a lot more than finance. It could also change how software is built and upend a bunch of today's biggest web companies and Bitcoin was designed this way to make sure that the same Bitcoin, which has no physical form, isn't spent twice by the same person.
I also agree with it. Physically bitcoin had a new one to be able to use by many of us. And bitcoin will really change a lot of everything that could be use for everyone of us. And it's become that easy way. And it's best really trusted.
