If a sale does not go through, the app shows a short message. Here is what each one means.
Insufficient balance
You are trying to sell more than you hold. Tap 100% to fill in your full balance, or enter a smaller amount. Coins from a deposit only count once the deposit is confirmed.
Invalid amount
The amount is zero, empty or not a number. Enter a value greater than zero.
Pin not set
You have not created a transaction PIN. Set one up, then try again.
Incorrect PIN
The PIN does not match. Try again carefully. If you have forgotten it, read I forgot my transaction PIN.
Unsupported Asset
That coin cannot be sold right now. See which coins you can sell.
Duplicate transaction request detected
The same request was sent twice, usually from tapping Proceed more than once. Check History before trying again; the first request may already have gone through.
