A: A 51% attack — rare for Bitcoin but possible for smaller POW chains with low hashrate.

Ethereum’s hashrate is irrelevant post-merge (2022), but other POW coins like Kaspa, Litecoin, and Monero maintain smaller but stable hashrates. To stay profitable in 2025, miners use these devices: hasratein 2025 hitprime s03 epi 13 wwwmoviesp 2021

A: Use sites like Blockchain.com, CoinWarz, or Mempool.space. 10. Conclusion: Hashrate Is the Heartbeat of Proof-of-Work In 2025, hashrate remains the single most critical metric for any proof-of-work blockchain. It represents real-world energy input, security investment, and miner commitment. While Ethereum left POW behind, Bitcoin and other coins prove that mining — when done efficiently and with renewable energy — can coexist with environmental goals.
