I am sure bitcoin can give many investment and shopping opportunities to the world economy and financial exchange systems.
For sure it is making an impact in the life of people. When i always speak of making the world a better place ,
my focus is on the people within the world, how comfortable their life becomes and adapt to the changing world. and this is what btc is providing granting the people freedom in finances to better their life. In deed cutting off the stress of transaction and making it convenient and easy for all. Surely with time the world will behold the truth.
It's really simple in fact and i enjoy this kind of questions because you don't come looking for profits only.
There are some aspects in which Bitcoin will make this happen if adopted by enough people:
Privacy: If done right, you can trade without anybody looking at your transactions like it happens with a bank.
Decentralization: Bitcoin is decentralized by nature which means that no big bank have control over all the currency available, taking power out of them and giving it to the people. However, believing Bitcoin will make banks disappear is unrealistic. But a good amount of people will benefit(The ones who decide to use it).
Easy Transactions: This could be a cause of surprise for someone who has a comfortable way of trading their money. But in some places where it's not that simple for any reason you can trade with someone else really easily, especially if you know the person. And that without mention some high fees we face with banks wich are reduced with the use of Bitcoin.
Security: Security will always be in your hands, that can be very good or very bad but it would definitely make the people having them worry more about the security of their Bitcoins which is ultimately good for all of us since virus spread so easily precisely for lack of security awareness. No more worries about someone robbing a bank(in countries where you are not protected), they can't get your Bitcoins if you know what you're doing even if they get your wallet.
Ultimately the Blockchain technology(In which Bitcoin is based) is something that can be implemented by governments and anyone who deals with data online, since it moves and stores blocks of cryptographically validated data that’s incorruptible. Which means transparency in any transaction, financial or otherwise.
The benefits are multiple and who will benefit is the whole human kind
