What a deal! Let me see if I understand. Assume one has 10k at Blue Marlin. So, you have to send another 10k to a new outfit. That is 20k. Then, you have to give then 200k of action. At an expected loss rate of 5%, you lose 10k in this process. Then, if you are lucky, they send you 10k back. Gee, why bother, you do not get any of your Blue Marlin" money back.
What a racket. This is orchestrated stealing. How to sell/buy 500 k in post up funds for nothing. These thieves are all in bed together. After the rollover, if the buyer happens to lose money, the seller will conveniently make him whole. Conversely, if the buyer makes some, he may share some with the seller.
In summary, you can piss away 500k of post up funds but have the guy next store bail you out for next to nothing. Beautiful, just beautiful.
