How to really execute the core and satellite strategy?

I’ve been researching the core-and-satellite investment strategy and feel it aligns well with my risk tolerance. For those of you currently executing this framework, I have a few practical questions regarding allocation and rebalancing:

\- What does your satellite allocation look like? Are individual stock picks generally too complex for retail investors? Right now, my satellites consist mostly of sector ETFs, along with very small LEAPS call positions when I feel strongly about a specific company. Do you allocate any portion of your satellite to Bitcoin or gold?

\- What is your framework for rebalancing when the satellite underperforms? Rebalancing is straightforward when the satellite outperforms the core, just trim the winners back to your target weights. But what do you do when the satellite drops? Moving funds from the core to the satellite feels counterintuitive. If you top it up with new income to restore the 80/20 target, aren't you just funding your underperforming choices? how do you handle this if you have no new income to inject?
