When you see the error 'Account not available' displayed in the trading bot output of your Coinbase trading bot, it means that you are not allowed to trade the selected quote currency or one of the selected cryptocurrencies under 'Currencies and amounts' in the Base config based on the country/jurisdiction where you reside.
If you encounter this issue, check whether you see the error for all currencies you trade or only for a specific cryptocurrency. For example, if you live in the USA, you may use USD as the quote currency but not EUR. Generally, for selected currencies under 'Currencies and amounts', privacy tokens are usually not allowed for trading.
