Deposits to these addresses will be added to your Spot Account Wallet which is directly used for Spot Trading activity. Should you wish to trade on Futures or Margin, you can simply make an internal transfer from your Spot wallet → Margin/Futures wallets once the deposit is confirmed. I hope that answers your question.
Thanks for the comment. I am currently fetching the addresses only for the purpose of tracking. As I understand it, the deposit addresses can change and are not sufficient for this purpose. Do you know how I can obtain all the addresses related to e.g. my eth trading history?
