Of all the risks written by the op, the one I'm most worried about is speculative risk, which in my opinion, often happens like a bubble because of issues created by whales.  At this time, the market is still very new to dealing with sensitive issues so that prices often go up and down until the difference is very large.  Sometimes the government and the market are not much different.  If you follow the market, then who has the most money will have a big influence in the market so it will be easy to create issues that will increase profits.
