Currently, the auto-compounding feature only applies to the XLD pool. In order to re-stake your earnings to other pools, you need to do so manually.
This feature will be upgraded in order to enable the ability to allocate a percentage of your earnings to any other pool (Zero or more).
For example, the below configuration would re-stake 10% of your earnings to the XLD pool, 50% to the BNB pool and the remaining 40% to the BTC pool:
10% XLD pool
50% BNB pool
40% BTC pool
