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.
Yes, I agree with you what you said because bitcoin can control the world economy.
First of all, you two need to read about definition of Bitcoin. Bitcoin can't not control the world economy, actually bitcoin is effected by world economy and opinion of some experts like Jamie Dimon. Bitcoin isn't a weapon too, it can't hurt anyone so if you say bitcoin is a weapon that make no sense.
That's true. There's no way bitcoin will control the world economy. Bitcoin is not created to become competitor of the world economy but rather can help the economic growth through the people who invested in it. Bitcoin investors will someday become rich and if you are rich, of course you want to buy many things right? So in that way, buying products for your family, materials for building your own house and etc can help increase the economic status because you are the product of bitcoin. You became rich because of bitcoin.
