I understand that times are tough for Juan and many others in your community. It sounds like he is in a difficult position and is trying to sell his ECOBANK tokens to raise money.
I think it is a good idea to let the market decide what the tokens are worth. If there are people who are willing to buy them at a price that is fair to both Juan and the buyers, then that is a good thing. It would also help to prove the concept of ECOBANK and show that it can be used as a way to store and transfer value.
However, I also understand your concern about violating the sacred trust in the project. It is important to be transparent about what is happening and to make sure that everyone is treated fairly.
I think the best way to do this is to have a clear and public explanation of why Juan is selling his tokens and what he plans to do with the money. This will help to reassure people that the project is still sound and that Juan is not trying to take advantage of anyone.
