You should look into universal basic income, if you haven't already. If you look into UBI you will find some ideas that pretty much align with what you are suggesting. There are also practical experiments, both past and ongoing, looking into the matter. Using a cryptocurrency as means of distribution would of course lend itself to the idea, but it's not an easy problem to solve, especially with both UBI and cryptocurrencies being rather unexplored fields.
Here's a list of pilot projects that may interest you:
https://en.wikipedia.org/wiki/Basic_income_pilotsI 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.
Of course there are a lot of passion jobs where money is secondary, but at the end of the day they still require money to continue their work. You can't just look at individuals in isolation without their socio-economic surroundings.
Also note that while researchers may not be in it for the money, a lot of them still get paid fairly well and rightfully so.
Point being, it doesn't matter if parts of the population don't care about money. As long as there are
some people striving for wealth, they will try to exploit the current system. And if they are able to exploit the system, that's exactly what they will do -- at the cost of everyone else who "doesn't care about money".
Even if your main intention is to spread wealth evenly amongst the populace, as long as there are some angles to exploit or positions of power to obtain, the approach is prone to failure due to human nature. Case in point, every implementation of Communism so far either digressed into a dictatorship or some form of centrally controlled capitalism.
Communism is easy to romance with if you never lived in it, but it's not a pretty system due to being relatively easy exploited from the top down. Maybe even moreso than Capitalism.
That being said, I'm convinced that due to technological and economical progress, some form of UBI will become a necessity in the future. It's going to be a very hard problem to solve though, regardless of whether it will involve cryptocurrencies or not.
