Too many questionnaires like this. You should define EXACTLY what you mean and give details. As the plan has changed so often, many might be no longer be aware of the buyback promise which was published on the website, but was then removed. Of course there are sources which document this, but please explain this with facts. People who signed up under this promise should be respected.
Yes, Dani said that buyback had been officially discontinued at the moment and the subject needs to be discussed whether to restart. However, the buyback promise which was initially made should be upheld for those owning up to the time that this was removed from the web site. That was a reason for many to invest in the project as it gave them confidence.
I hope people are starting to realize the chaos that ensues when constantly rapid changes are made.
