Bitcoin's potential surge to $100,000 is exciting news! As Bitcoin grows, certain altcoins might benefit from the momentum. Here are four altcoins that could be ready to rally:

1. *Ethereum (ETH)*: As the largest altcoin by market capitalization, Ethereum often follows Bitcoin's trends. With Ethereum's transition to Proof-of-Stake (PoS) and growing DeFi ecosystem, it might benefit from Bitcoin's surge.

2. *Polkadot (DOT)*: Polkadot's unique interoperability features and growing ecosystem make it an attractive option. As Bitcoin grows, Polkadot's potential for increased adoption and usage might drive its price up.

3. *Solana (SOL)*: Solana's fast transaction times, low fees, and growing DeFi ecosystem make it a strong contender. With Bitcoin's surge, Solana's potential for increased adoption and usage might drive its price up.

4. *Cardano (ADA)*: Cardano's focus on scalability, security, and sustainability, along with its growing ecosystem, make it an attractive option. As Bitcoin grows, Cardano's potential for increased adoption and usage might drive its price up.

Keep in mind that cryptocurrency markets are highly volatile, and prices can fluctuate rapidly. Always do your own research, set realistic expectations, and never invest more than you can afford to lose.
