This feature is optional so you would firstly need to activate your payment routes for deposits.
You would then need your Bottlepay account number and sort code which you can find by hitting Fund -> British Pound -> Manual transfer from the home screen (or by tapping your profile in the top left corner of the home screen -> British Pound -> Manual transfer).
This will allow you to setup a standing order from your bank to your Bottlepay account. As soon as your deposit hits us it will automatically convert to your BTC account without having to trade.
If you are from the UK you can use the open banking feature. To find out how to set up an open-banking deposit click here
