Not sure what this line exactly means.
I was referring to Withdrawal limits potentially being an obstacle, but there's a chance I have misunderstood how the DEX will work.
The LP node won't have to withdraw in order to complete the trade. When someone buys from DEX the funds will be sent from the LP node's local wallet. In other words, the LP is keeping funds in both DEX and a centralized exchange.
It's just like arbitrage between two centralized exchanges, but in this case the other one is our DEX.
If you buy KMD from DEX then the LP will send KMD from its local wallet and balance the trade by purchasing more KMD from the exchange. If people buy more KMD via DEX than they sell, then the LP node can balance its books by withdrawing more BTC to its local wallet.
This is a good idea and DEX will be a independent exchange . We can buy and sell on itself and therefore we can support the price and volume change for our coin . it can help us control issues happening in our exchange.
