Well, you have asked a lot of questions within a small scope of this thread. But let me try to answer.
Is Bitcoin really a such innovative thing that can change people's lives significantly in the future?
I think we still live fine without having Bitcoin being actively used in our real lives.
Indeed it is a life changing concept! However, it depends on how you look at it. Majorly, bitcoin is used as an investment contrary to its initial idea. But we have loads of examples where people were able to achieve succes through crypto trading or just by investing in it. We have negative examples as well but these people tried to become rich overnight. So it's a mix of good and bad experiences like most other things of the world.
Bitcoin is not being used actively in many countries. But here the issue lies with the legal framework of that country, not with bitcoin. It is fully capable to be used actively but due to unfavorable legislation, people are not able to!
Oh well... In terms of transparency, i can take on Bitcoin's technology.
But which one is it that raised its value so much though?
Technology or People's attention?
It's both! The anonymity is one of the major factors behind the popularity of bitcoin today. So first came the technology which caught people's attention and then comes the popularity. This popularity is what driving bitcoin today! Makes sense?
