This is just an analytical question, not blaming nor scapegoating:
1. Who do you think have biggest responsibility on making those prices fall and keep down?
Whether the governments, the big sharks (some players with huge capitals), or purely the market?
2. Whether the ones who made it fall is the same one who keeps it down or not?
3. And what to do make them bounce again, although slowly?
Please remember, this is just an analytical question. Not supposed to blaming nor scapegoating any party.
