Yes, we do share the vision of a basic income, an unconditional income distributed to everyone.
However, we don’t share the idea of a basic income that would replace all income or even that would be sufficient to live.
We would not even speak about it because the value of such basic income can’t be decided. Value is different for each human being so, “what do you mean by sufficient?”.
The basic income of ucoin is what we call a universal dividend, it’s is the exact share of all the money creation (within space and time dimensions) between all the members.
To respect the freedom of the members, in the sense of free economic system, they have to be able to use the money they want. So surely any member could ask for joining any group and even create his own currency if he wants. That doesn’t mean that he will be accepted in every group, and it doesn’t mean that he will find every time someone who is willing to exchange a specific currency in an other one. All coins can be traded if you find someone to trade it with you. ucoin will not assure the trade of any currency, but will indeed allow you to do so if you find someone who wants to trade with you.
I hope I answer well all your question and I invite you to read the few english references available. I hope for you the RTM will soon be readable in english.

Have a smiling day,
