You can view your Bitcoin, Ethereum, Litecoin, or other cryptocurrency address by tapping on the Receive button while inside your selected wallet.
At the Receive Screen, you will see a QR Code which you can show other people, allowing them to scan the QR code, input the amount of crypto they would like to send, and then send that crypto to your account.
Below that is a long string of text which is also a copy of your address. You can copy the text-based address and send that out as well, allowing users to send payment to that particular address.
The address is case-sensitive.
