I believe that Bitcoin is changing our world. People around the world started to realise that current financial system isn't good at all. Paper money is worth basically nothing. Authorities can print additional money if they want to, leading to inflation. Bitcoin is great because transactions are transparent (not necessarily every transaction is anonymous) and everyone can participate in the network growth (by buying and maintaining ASIC miners). Bitcoin as a currency would make us independent from banks. Paying would be even easier beucase we would use our phone (scanning QR codes or NFC) instead of using a seperate debit card. I hope the revolution will start soon.
Although It is still very difficult for bitcoin to change the entire world, but no doubt that it is really changing the life style of some people. Specially for those people who do not have a day job or if they cannot fulfill their needs, I am sure that if they will adopt bitcon,
