In 2025-2026, Ethereum mainnet fees for simple ETH transfers average $0.10-$0.50 during low-congestion periods. Bitcoin fees vary widely based on block space demand — ranging from under $1 to over $50 during peak mempool activity. For regular transfers, both networks are now more affordable than their 2021 peaks, but neither matches the near-zero fees of Solana or BNB Chain.
Solana charges approximately $0.00025 per transaction regardless of complexity — making it 1,000x cheaper than Ethereum mainnet for simple transfers. BNB Smart Chain averages $0.05-$0.20. Polygon (PoS), while an Ethereum sidechain, offers transactions under $0.01. However, none of these alternatives match Ethereum decentralization, security, or DeFi ecosystem depth.
For maximum security and access to the deepest DeFi liquidity, Ethereum mainnet or its L2 ecosystem remains the standard. For cost-sensitive high-frequency trading or gaming applications, Solana or BNB Chain offer compelling economics. For most users in 2026, Ethereum Layer 2 networks like Arbitrum and Base provide the best combination of low fees and full Ethereum security.
