Answer: It sounds like you may have experienced a loss when swapping your 10 XTZ of DOGA. This could have been due to a number of factors, such as the price of DOGA changing, or the pool being empty. If the price of DOGA has decreased since you purchased it, then this could explain why you have lost some of your XTZ. Alternatively, if the pool was empty when you attempted to swap your XTZ, then you may have been unable to complete the transaction. It is important to check the price of DOGA and the pool status before attempting to swap any XTZ, as this could help avoid any potential losses.
