Please let me chance to show my past post to help you out.
The wallet supports change address too.
Additionally, you can import BTC address you get from Bitamp to other wallets, such as Electrum.
On Bitamp, with each receiving address, you will have the key icon, click on it to get private key for that specific address.
Below is an example for you. You should never disclose your private key like that.
On Electrum, click on File > New/ Restore > Import Bitcoin addresses or private key:
- If you copy and paste your BTC address from Bitamp, you will get an imported, watching only on Electrum.
- If you copy and paste your private key from Bitamp, you will get an imported wallet on Electrum.
Name your wallet file and set up a good password on Electrum when you import it.
