PEERAGE
Tokens with high correlation to BTC are of course $LTC and $BCH . Both tend to follow its trends, albeit with varying synchronicity, as they iterations of it.
In fact, both were technically the same as the initial/primordial #BTC (early forks), with improved metrics (limited supply, PoW, blocksize and transaction speed) and not burden by ordinals.
The focus exclusively on being a payment network and not an all-in-one ecosystem, is inherently positive but deters speculative interest, hence both LTC and BCH's lesser status is due to lack of mass adoption more than anything else.
Their Relatively Low volume translate into higher price volatility, which in turn provides the kind of rare opportunities BTC infrequently does for being more stable (which is a positive thing for capital preservation but not for turnover).
As tradable assets, LTC and BCH have shown a remarkable resilience and ability to recover.
Panic depresses their price more severely than warranted by news.
Some exposure to BTC through them has been rewarding. They might seem static, but are not.
