Bitcoin has changed how finance industry has worked. BTC forced the white collar people with rules and regulation to accepted the free and revolutionizing technology.

This is just start CBOE, CME and next will be more coming.

In my own opinion, Bitcoin is not changing the world. Bitcoins can be used by anyone even for better or for worst and what i only mean is that the world revolves depending on the people who are living in it if it will be a nice place to live or it will be a very unpleasant place to live on.

Yes bitcoin is changing the world, it changing the peoples life. It helps people to have a good life. I see some of my friends really changed their life because of bitcoin. So now i really want to change our life, bitcoin please help us 😄 So if all people will have knowlege about btc. It will really change the world

Yes if i may say...A friend that introduced me into bitcoin has been testfying before ientered and has also recorded another smile of money yesterday.Bitcoin is really changing the world and lives.

Yes bitcoin changed our lives but i don't think it changes the world. It changed our lives when it comes to financial status and changed our economy in a better way. As our financial status gets better the better our economy will be but i don't think it change the world because we can't changed the fact that the world is getting worst, poverty is getting worse as well as the mulnutrition, corruption and such things.

Slowly, but it is happening!  So, yes bitcoin can and would change the world and I think in some countries bitcoin have already played a very big role in their economy and its also reduce unemployment in some countries as well! So I hope governments will not screw us all!   

Well for me I think the word won't change but the people who uses bitcoin will be the one who changes because we know that a lot of people change because of money.

 From my point of view, bitcoin really changed the world, especially in me.it is free and open worldwide, decentralized currency, anonymous, with low fees of transactions, and also having a big community supporting it. it made me become totally self-sufficient. before meningeal bitcoin, I always depend on others in matters concerned with money. but, since knowing bitcoin, it made me become more independent.

I agreed, as you mentions, becasue bitcoin has changing our business style and it effect on our living way. Then definitely bitcoin can change the world. But i can't say it properly that bitcoin can change the whole world, but our bitcoin users 100% certain on it that bitcoin has changed their financial life.  

In the early times, the understanding of currency was a hand held piece of paper that is used for purchase, in which security was an issue. Handling physical materials like paper or some metals that has a value, keeping it by your side all the time takes some risk. But in todays world the idea of storing value digitally, the cryptocurrency, give a more secure and reliable transactions. That's were Bitcoin changes the world, changing the way we handle, secure, and transaction for money.
