It is not hard to see that the profit of "Rijinbao" comes from the delayed delivery fee of 5 per thousand per day. To maintain this source, delivery must be limited. Thus, pan-asian "rules" allow individual investors to apply for delivery by the buyer without the seller's qualification for delivery in kind, while producers with seller's qualification for delivery are not allowed to participate in the trading of related rare metals in pan-asian markets, and that producer may be the only one qualified to deliver on a rare metal, which means that even if the bulls choose to deliver in kind, they will not be able to get the goods. In the long run, investors rarely dare to hold empty orders, deferred delivery fee income is also getting less and less, but the "day Jinbao" scale has been expanding, the original envisaged revenue model will be difficult to continue.
