You made really good point Bitcoin is very different from other cryptocurrencies because it truly decentralized and can not be easily controlled which is why it stays strong and leads market mostly seen as digital gold.

While some altcoins might have brief surges many people doubt they will reach their past highest prices again anytime soon. This is because money tends to flow back to Bitcoin especially when market is uncertain and altcoins mostly struggle to grow unless they have real world uses and strong communities.
