Suppose, I want to make market for bitSilver. I borrow 1 bitSilver into existence and place an order to sell it for BTS. After this, I can't place sell orders on other markets, Silver:USD, Silver:CNY etc... This is wrong. This removes liquidity from DEX. I should be able to place sell orders for 1 silver on multiple markets, and if one of them is (partially) filled, all others should be automatically updated to adjust to my available funds.
