Some media shows that bitcoin can be the next weapon to control the world economy. i think it is true and it will be seen soon.
In my opinion, bitcoin is considered as the tool for payment. It would be the next future currency. We don't have to carry cash when going out. It would reduce the time of the transaction as well as securer. Whenever it got accepted in all of the countries, the economy would be promoted significantly. Because we only use bitcoin like a common currency for trading everywhere in the world.
Once you're addict of something you'll never leave it. Same with bitcoin once you don't pay tax you'll never pay to government it can ruined the economy for sure.
