Kraken now has a simple feature in which you can convert all asset balances below the minimum instant buy/sell order size (approximately 1 USD). With this feature you can convert your small balances into any cash currency of your choice, for example EUR or USD.
What are small balances?
Small balances are considered balances below the minimum instant buy/sell order size (approximately 1 USD) of an asset in your account. These small balances can arise due to leftovers from amounts entered to trade or withdraw from an account.
Please note: You can only convert small balances once every 24 hours
