The exact time when a member's coin buy or sell order transaction will be successful cannot be known with certainty. This is due to several factors that affect the transaction process. One of the main factors is the transaction method used by the member. In addition, the price of the coin buy or sell order listed also plays an important role. If the specified price matches the best price in the orderbook, the transaction will be successful immediately. Conversely, if the price does not match the market demand or supply, the transaction may take longer. The volume of coin trading in the market can also affect the speed of the transaction. Another factor to consider is the liquidity of the coin at the time of the transaction. Therefore, members are advised to always monitor market conditions in order to estimate more effective transaction opportunities.
