The Ethereum 2.0 update, completed with the Merge in September 2022, shifted Ethereum from Proof-of-Work to Proof-of-Stake, ending traditional mining. Small miners can no longer mine ETH, rendering their GPU and ASIC equipment obsolete for Ethereum. They face three options: switch to mining altcoins like Ethereum Classic or Ravencoin, stake ETH as validators (requiring 32 ETH), or sell their hardware. Altcoin mining is less profitable due to increased competition and lower rewards. Staking offers 6-7% APR but requires significant investment. Many small miners may exit due to reduced profitability and high costs.https://www.boxmining.com
