Many problems are solved with bitcoin, economic problems, such as reducing unemployment, improving one's finances, and I think indirectly help the state economy for its citizens who follow bitcoin.
How Bitcoin reduces unemployment, I would like to here that? When bitcoin shut down all the banks and financial institutions where will people work? If you are not computer geek, programmer it will be hard for you to find a job in the future.
Bitcoin will not save jobs, bitcoin will not end work poverty, bitcoin is a tool that can help global economy because world needs decentralization! Circles of powerful people are small, few people run whole the world, with blockchain and bitcoin we will be able to know what is someone doing and how, everything on a table is a recipe for a better future. Decentralization can give a power to a little people accros the world, why would I go to bank and let them fuck with my brain, earn from me when I can use bitcoin and help people around the world who mine bitcoins, why to not give a power to a little man? That is bitcoin doing and that is the advantage bitcoin have over fiat system.
