Your best bet will to create a coin like Ripple. The government pre-mine all the coins and they give out addresses to everyone. Every month they distribute a small amount of coins for free to every person that registered with their Alt coin.
Ripple pre-mined billions of tokens and gave it away for free to their founders, but ComCoin will distribute it evenly between all citizens or members of the global communist party.
Russia and China will love this coin, because it gives them full transparency and control.

Your comment is the kind of stuff I wanted to read here. Ripple or Freicoin (like other users said), can't be compared with my idea, distributing to new users or distributing to miners is not the same than distributing to all active users, these are totally different use cases.
I see that nobody here knows how a socialist or communist person is, you guys never talked to one I notice that, that is why you say nobody will be motivated by the currency, not all people in the world is motivated by the money like you guys, for example think about almost any scientist or a lot of students, they don't learn and do science for the money, they do it because they like knowledge, and that is just a quick example.
I'm a poor guy from a 3rd world country, try to imagine how hard is to be a poor worker and keep motivation, so I'm already unmotivated, specially in this world where 1% of the population owns more money than the rest of the population together, they own the money that intelligent people needs to improve the world, I see all the time very intelligent artists and scientists that don't have the money to do stuff that would benefit the world, only a few can get money from the state or a company, You never lacked money for what you needed and that made you live in a fishbowl, never talking with poor workers.
There is nothing more useful for a lot of people than an idea like this working, and not all the people will like it and that's OK.
It is not that they do not know how socialist or communist systems work. They just know more about Capitalism and they know this will not work, when nobody is buying these coins. Crypto currency gets value when people compete to buy it on a open market. In a Socialist system, the government will have to determine the value and then give these coins to people for free.
There must be a total mind shift when you are dealing with a socialist system. The government controls the economy and the money and they dish it out equally to everyone. This is not what I want for Crypto currencies. ^sad^
