Real-time is best; But generally higher than the actual exchange rate. For investors, most of them lose money. After the loss, the exchange rate will be gone.

For example, if you invest 1 10,000 RMB, if the real-time exchange rate is 1 USD =6.4358 RMB, there should be 1.553.8 USD; Many platforms deposit money at the exchange rate of 7.2, and 1 10,000 RMB is only 65,438 USD+0.388.8; This is equivalent to a loss of 164.9 USD.

Although the withdrawal is still in accordance with 7.2, once a loss occurs, the exchange difference of the loss part will be lost in vain.
