EPISODE 82 — What Are Gas Fees — and How Do You Avoid Paying Too Much?

Gas fees are the transaction costs you pay to use a blockchain — and if you have tried to interact with Ethereum during periods of peak demand, you may have paid twenty, fifty, or even one hundred dollars for a single swap or token transfer. Gas fees have frustrated users for years, pricing ordinary people out of DeFi, creating unpredictable costs that make applications feel unreliable, and pushing entire communities toward cheaper alternatives. In 2026, with Layer 2 networks now dominant and mainnet fees down from historical peaks, understanding fees and how to minimise them is more achievable than ever.

In this episode of Crypto for Beginners, we explain exactly what gas fees are and where they come from. We cover the computational resource model: every operation a blockchain executes has a gas cost, and the total gas for your transaction multiplied by the gas price determines what you pay. We explain Ethereum's EIP-1559 fee mechanism introduced in 2021: the base fee that adjusts automatically with network demand, the priority fee you add to get faster inclusion, and how burning the base fee creates deflationary pressure on ETH supply over time.

We explain why fees spike during NFT mints, token launches, and market volatility events — and why the same transaction can cost ten times more during peak hours than at three in the morning UTC when demand is low. We then walk through every practical strategy for paying less: using Layer 2 networks like Arbitrum, Optimism, and Base where identical transactions cost fractions of a cent; using Solana for everyday activity at near-zero cost; timing mainnet transactions for low-demand windows; setting custom gas limits; and using gas tracker tools that show real-time network conditions. We cover which transactions genuinely require Ethereum mainnet and which ones you are simply overpaying for out of habit.
