For any reason any government can shut down trading with their currency not under their control. That means as long as alt-coins are attached to fiat currency be it the dollar or euro ect. The fiat currency has control of all alt coin.
Now if the alt coins were attached to hard assets like gold , silver, or a extensive barter for goods system, and is not exchanged in any government fiat currency I would say yes its a free driven system.
I think the question will be most countries are working on their own block systems and when they get done will they allow trading with other non government systems
Okay, I'm a bit confused by your assessment of the situation regarding alt coins and hard assets. Hard assets, such as gold and silver, have always been controlled by the governments of the world...the federal government in the U.S. even confiscated gold from every citizen who had it at the time...so how would that create a "free driven system"?
Hard assets are anything of value that are in YOUR possession, gold and silver being an example of large value per size vs per say a 64 corvette. Gold and silver was so easy to hide back then because there were few records of sales the GOV had, many did not give theirs up that was in their possession.
A lot back in those days converted their gold and silver to assets that the Gov could not touch, to transfer the risk of getting caught to those that did not care and saw it as easy assets. Example where I grew up back in the early 70s there was a old german couple that did not have any children and lived very quite on a large farm. After they both passed away the state went in because of no relatives and found over 4 million usd worth of antique cars in the barn.. Hard assets... Today he could have backed 4 million usd in crypto with those assets.
Either you personally would have to have trade in hard assets with your coin or the exchanges would have to have hard assets to back up the exchange, so it would have value.
Otherwise its a ( free driven system ) controlled by the countries fiat currencies its exchanged at and can be shut down very fast by those countries saying that it is illegal to purchase crypto with their fiat currency within the boundaries of their country for security reasons.
The point is to keep fiat as a base of exchange out of it. Anything that keeps the GOV hands out of it. If their hands are in and tacked to something like a fiat currency. Then the system is only a ( free driven system ) as long as the GOVs that own those currencies want it to look like it is.
It would be a very hard system to create for it would challenge fiat and I do not think they would like that. How it could be done is something I would have to think on, main objective would be getting away from fiat. To truly be a "free driven system" it can not ride on the backbone of a countries fiat and be considered free. Or i guess you can call it that until the countries say otherwise.
