Why does my account balance not match the previous balance when I haven't played any games?

This usually happens when customers deposit using cryptocurrencies. Due to the volatility of the cryptocurrency market, the rise and fall of currency values ​​will directly affect the value of the customer's balance. Therefore, even if the amount of cryptocurrency in the account remains unchanged, if the customer has turned on the fiat currency balance display function, the total value of the account balance may fluctuate with market changes.
