There is no limit to the amount of sell orders you can place per day.
There is only a limit per sell order to guarantee the set price.
This means if you want to sell 20,000.00 euro with a limit of 5,000 euro per order you can create 4 orders to completely sell your 20,000.00 euro worth of cryptocurrency.
LiteBit cannot withdraw the cryptocurrency from your own wallet. The customer needs to send the cryptocurrency within 15 minutes to have a smooth transaction.
