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.
I can respect your opinion about Bitcoin, China is afraid of Bitcoin that's why they want to ban all the Bitcoin exchanges and start them with a legalize format. If not it can affect their economic growth because already the Bitcoin is generating billions of trading volumes in the market.
