When you view your balances in the accounts dashboard, you can see an estimate of your balance in either ZAR or NGN. 

When using a device with a smaller screen you might have to click on the blue widget next to the currency logo and the details will be visible.    

Remember that this is an estimate based on the current trending price and you can sell your tokens at any price as long as there are buyers willing to take your price.

Please note: This feature only works for the currencies with have ZAR or NGN trading pairs on the platform
