If you're looking for a cryptocurrency that operates independently of Bitcoin's fluctuations, you might consider stablecoins. Stablecoins are designed to maintain a stable value relative to a fiat currency like the US dollar. Examples include:
1. **Tether (USDT)**
2. **USD Coin (USDC)**
3. **Dai (DAI)**
These coins are pegged to fiat currencies and are generally less volatile compared to Bitcoin. They can be a good choice if you're looking for stability in the crypto space.
