It not that impressive, over 5k are his own coins he transferred from J-D alone. Maybe he did manage to scam some but the idiots deserve to lose their coins for being stupid.
It's pretty much all his BTC.
It doesn't make me feel better.
Well somewhat I feel better about myself because I'm not going to create a scam like that to take so much easy money... but...
Because anyone can scam, scams have no barrier to entry. That means the competition is atrocious, which drives the margins down while increasing capital costs. That means they need more and more of their own BTC (seen above) for less and less income. This last attempt is characteristic, in that it took ~6k BTC from the "business" to generate < 100 BTC in "investment". Which isn't (at least usually) all gravy.
With an ounce of a clue he could have made more by being honest, which incidentally is always the case, it's just that scammers have little clue and little desire to learn, otherwise they'd be crowding -assets rather than falling over each other in 1500 page long threads about watching MtGox/Asicminer/whatever.
In a sense scamming is not much unlike Bitcoin mining, in that a desire to get something for nothing drives people into the unsustainable commoditization march. Soon enough we'll be having people offering the whole palette of scammer "services", from shill posting of "certified" quality to "Bitcoin verification services" where you pay some guy a Bitcoin to move 5000 of them from an address of his to another address of his and give you something signed with that latter as if it were yours. On second thought...we already have these, don't we.
(see my earlier notes on those)
