I agree with you transisto, I personally think it strives against the "give & take" idea the whole system was invented for. In my opinion to put a price tag onto the aspect "give" will hurt this project. Imagine a real life scenario in which meal vouchers are handed out as support to poor. Sounds like a fair setup and a caring community.

Now comes a group in that sees bigger earning potentials here, they use their reputation in order to get big chunks of the vouchers but instead of giving them away for free they put a price tag on them.

The sellers will benefit in this scenario but the broad mass, which needs the support the most, will suffer.

In longterm the project will suffer. Dropouts, tough environment for newbies and a massive amount of poor content (as token buyers will not need to worry as much about the quality).

This project in my opinion pressurizes the caring aspect, which is needed for further growth. Users should feel welcome here and not pressurized to buy externally tokens in order to have success here.
