For me it is the blockchain technology which can change the world. Using blockchain technology as an upgrade to most financial establishments like banks, will lead to ease of access and efficient monetary transaction. I have read some articles that IBM and JP Morgan are already introducing it as a new system.
Yes bitcoin is a new emerging technology and i think that with the passage of time it will become more developed and become more advance, in modern time it is expected that crypto currencies are going to be more popular even some people are thinking that it will replace fiat currency but i think that it will take a lot of time because currently very little people have knowledge about bitcoin and other crypto currencies.
