Newbie question about exodus wallet!
Here is the explanation: https://support.exodus.io/article/81-how-do-i-generate-a-new-bitcoin-address


  Your bitcoin addresses are reusable, however, some users may want to
  generate new bitcoin addresses for privacy purposes. If you would like
  to generate a new address, click on the arrow to the right of the QR
  code in your bitcoin receive window.
  
  You start out with two bitcoin addresses. As each address is used, a
  new one will generate. This way, you always have an unused address
  available to you.
