Why it changes
Gas fees can rise when network demand is high. Different blockchains also have different fee models.
Why it matters
Gas fees affect wallet transfers, swaps, DeFi actions and bridge transactions. They can make small transactions uneconomical.
Common mistake
Do not treat Gas fee in crypto as a universal rule. Exchanges, wallets and card apps may use the same term differently, especially around limits, fees, networks and account restrictions.
User action
