As we're talking about a crypto-currency, I guess we should define what "control" really means in this case.
It would have to be very different from the (so called) control that governments currently have over fiat currencies,
especially since we cannot (and shouldn't) change the original nature and philosophies behind crypto-currencies.
So perhaps the question is: how much influence on a crypto-currency would you accept from a government?
Ok thanks for that clarification , but with all due respect unless guidlines are put in place really a "cryptocurrency" could literally be anything , it could be existing without a blockchain , it could be Corporation issued as is the USD it could be "Government issued" .
obviously perhaps that is your intention to discover , I really hope it goes back to some sort of a Kernal of a proposal and i will be uber interested to see the results / progress .
Here is my general advice
I think that you will find that tolerance is fairly high .
if a government issued cryptocurrency was instituted weather it be a stop gap emergency instrument that then developed into an offical currency or, a preemptive issuance and some sort of integration.
if the currency is indeed equitible and serves the purposes of SME, ( the drivers of velocity in relation to " price" and " standard of living " ) .
And if the issuance is obviously pegged back to the principals of a "PoW" and protected against fraud " unlike fiat systems which are based on fraud" .
People will not generally understand of course unless they educate themselves , but they will be tolerant.
Wouldnt it be a nice " conspiracy" if the actual rational actors inside some of our government institutions were thinking ahead and thinking about national security .
Wouldnt it be nice if that resulted (in whatever way ) into a more equitible general system, which accoring to my calculations can only happen in the current information environment .
Then as per the " principal of multidimensional information continuance" the system must act inside the new information environment upon the new set of principals , this accoring to the principal then changes the environment and so on.
So indeed a system such as this could have larger positive effect than realized , and will be hard to game .
Follow up question id like forwarded :
What code , and will it be open source ?
^^^
We all know "governments" sensitivity around " privacy" and " domain" but I have to further advise cryptocurrency exists in a peer driven environment, while it is possible that a Gov issued crypto could survive close sourced , it will be at a great disadvantage , possibly a grievously disabling one.
Obviously cryptocurrency exists due to the need for it , some of this is mistrust and loss of confidence in fiat in general ( well founded) close source may have little if any better confidence.
