First of all, Bitcoin is not considered a currency by the U.S. government, so your argument about not being able to touch a country's money is invalid.
Recently, an article in
The Economist, titled
"One world, one money" from September of 1988 came to light, where the author is predicting that in 30 years [2018], a new world currency will prevail and be utilized globally:
Even though US will not consider Bitcoin as a currency it is still based on a $ value market cap.
The author was written the article 20 years ago or maybe this is the one you are pertaining to
http://www.anonews.co/rothschild-world-cuurency/ that was really written on 1988.
While I'm not a conspiracy theorist, I am a realist that likes to [over]analyze situations. The Economist is, and has always been owned or controlled by the Rothschilds. The Rothschild families have controlled world banks for generations. Control the banks and you control the world.
I used to laugh at anyone who claimed that the NSA created Bitcoin. I used to ask them why and how the NSA could create a trust less decentralized peer-to-peer currency that they have no control over, and what the purpose would be. But lately, seeing as exchanges are required to flip and turn over their customer database, and start implementing more KYC verification procedures, this could potentially have been the plan all along. It's highly doubtful that this is the case with Bitcoin, but it's not an impossibility.
The thing that truly makes me question the government's involvement? The network effect of the internet and when it was implemented. That's another example of something that was created by the government that they lost control over. Now they're trying to regain control (net neutrality), but we all know that it's too late. So could be the case with Bitcoin? Again, highly doubtful, but not an impossibility.
Conspiracy about Rothschild Family controlling over the world is too cliche(for me)
I think the active family members that are running the businesses is not that fully in control compare to the one that really started it all. It's quite obvious they already build an empire to which their family and future next generation doesn't need to work and think too much for maintaining the businesses so they are just leveraging it by hiring multiple financial people(maybe this is capable to control world) to do the work for them.
We can't blame those Rothschild's dynasty though as they are the one who pioneered this thing, I hope my great grandfather did it instead.
