Each Ballet wallet has a primary coin address as well as multicurrency support. You do not need to use the Ballet Crypto app to deposit coins to the primary coin address. Just use the cryptocurrency wallet app you want to send coins from to scan the primary coin address QR code on your Ballet wallet. But you do need to use the Ballet Crypto app to deposit other cryptocurrencies to your Ballet wallet.
