I agree with that post, the internet has caused a lot of losses by people being able to trade their own account online being duped by online bulletin board manipulators.
And now it has all stopped, the lambs have been fleeced, and there are no new lambs coming to the slaugherhouse!
Greed won, but is now losing as there are no new mug punters, and it will take time for the memory of the previous losses to disappear and a new breed of "investor" appears.
