Market orders are the most basic type of orders. They are considered to be the most reliable and fastest method for buying or selling bitcoin and get executed with the least time lag.
When traders execute market orders, that means they are prepared to buy at asking price levels or sell at prevailing bid price levels, thus sacrificing the bid-ask price spread.
Market orders, when executed, always pay the Taker Fee.
Please note: Market Buy orders follow the ‘best effort’ principle. As a result, even though your order form might show that you’re purchasing 1 BTC, actual order book prices and/or market depth combined with your available funds may mean that you will actually buy less than 1 bitcoin at the execution of the trade.
