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.
For now I think it is not possible. It's influence is not wide enough that we could say that it will have a large impact to the world's economy if there is a price movement of bitcoin.
I am confused bitcoin is anonymous we can use it anywhere we're hiding and no one can trace it.Does it really matter we don't use bitcoin if its not legal in your country?. My uncle lives in china where bitcoin is illegal he is still using it and making profit.
