Oh look... "Mr 796" (who -- let's drop the pretense -- is probably you, ZhuRong), is releasing forecasts in an attempt to influence his own futures market. Isn't this a bit brazenly unethical? One would think you would at least go to some lengths to hide what you are doing.
I'm sure this is all fun and games for your users -- a gambling site on which you can't lose! Until....
Even if that is not your plan, it certainly looks like it.
Funny that the "trend analysis" is "the most reliable". Who would have expected that?
Furthermore... the "stocks"... which you issue (for free!) and (it seems) plan to trade on your own market? Will people fall for that? Are people actually that naive?
Again, even if your intentions at the outset are good, you should not be putting yourself in this position (and your users should be aware of the great danger they are in).
