Yes. That is why it is hard to believe that there are people who really want to bring it down.
It is a new world and technology is soaring high. There will be more upgrades with the upcoming years and everything now can be found on the internet.
Bitcoin is part of the internet world so most likely it will be the most used someday.

What's really changing the world is the Internet. Bitcoin is just a part of it. On the Internet, there's social media. Right now people are living in that world. People are living in a world where validation and acceptance from other people matters the most, and that's just a small part of the Internet. On the Internet, people are interacting every single second. We get to talk to Internet celebrities and feel great about it. Internet is also the place where we buy and sell things. You want something or you want to sell something, you post it on the Internet. Bitcoin is nothing compared to how much Amazon and eBay is being used. The bitcoin community is nothing compared to reddit, facebook, and twitter. But all of those huge networks are just under one idea -- the Internet.

So OP might want to do some rephrasing in his post. The Internet is changing the world and bitcoin is just one of the many parts of it.

bitcoin provides a new idea in today's sophisticated economy and payment tools.
the higher the value makes everyone in it get a very abundant advantage. bitcoin also changed your life.

The good thing about bitcoin is that it is like an international money for all of us. One that has bitcoin can go to places without necessarily exchanging his current currency to that his country destination is using. For as long as he has bitcoin he can go there immediately and if there no stores that accept bitcoin as payment then he has just to exchange them to the country's money. Also, cryptocurrencies are already used as an instrument for large transactions because as observed, it has a huge value when it is being exchanged in fiat money.

Yes there is no doubt that bitcoin is going to change to world and as we know recently bitcoin is arrived to Thailand and end of the year some other countries will also accept bitcoin so demand of bitcoin is going to increase also its also playing a role in economy of different countries and some countries have already make bitcoin legal in their countries.

Yes no doubt that bitcoin is changing the world! With bitcoin it changes my life it makes my life better, so it is like an organization chart that it makes even  the one in the bottom to have a better life, so I really have a good faith in bitcoin and believe that if it changes my life it can change the world.

Yes bitcoin is changing the world but for a good cause. It helps the users. Gives extra money to employed people and gives money to unemployed people. It also depicts that our world is starting to innovate and transactions are starting to get easier and technology has somethinh to do with it.  Bitcoin offers possibilities and opportunities to it's users.

Yes, I believe bitcoin is changing the world by changing the way people live and changing their perspectives about money, like what you have mentioned. If bitcoin will be implemented and legalized all over the world, and everyone uses it, then it will change the whole world and it will change the way we communicate about business with other people.

I'm sorry to be the pessimist here, but what has bitcoin done to change the ENTIRE WORLD? In my eyes, bitcoin hasn't done much. So far the only thing I've seen bitcoin change is a few lucky people's wealth. But you would have to invest some. Bitcoin hasn't changed the way we're doing business yet. I believe bitcoin will change the world in a positive way, but I hasn't done anything significant yet.

Yes, bitcoin can change the world through financial aspect whereas many people help in that matter because they gave people to have a source of income and they gave all of us to make our dream come true. That is the start where our world was change by the bitcoin.
