So I can use one of the change addresses to receive funds?
As other members have explained, change addresses are regular addresses, and there is no difference between them and receiving addresses. So, yes, you can use them to receive funds, but is there any reason you need to?
When you click on the
Receive button in Electrum, it will generate a new receiving address that has never been used before (for privacy reasons). However, to use one of the change addresses, you will need to open the
Addresses tab, scroll down to find the list of change addresses (on mobile), and choose one that hasn’t been used before (if you care about privacy).
