Right. The potential market manipulation is subtle enough as not to be completely noticeable or provable, but also of big enough magnitude to be able to make a LOT OF MONEY.
If you had a mechanism to get a 20% return every month, anyone could get rich in a fairly short timeframe.
i have been trying to get 20% each month for a while now :) met my goal in april but jan / feb were not profitable so have alot to make up in next few weeks / months
