🧑🏫 Lesson 12: Gas Fees and Why They Change ⛽💸
If you've already tried sending a token or buying #nft , then you've probably encountered this mysterious concept — gas fee. Let's figure out what it is and why it keeps fluctuating! 📈📉
⛽ What is gas?
Gas fee is the commission for executing operations on the Ethereum blockchain.
Every action (transfer, exchange, launching a smart contract) requires computational power.
And that means — you need to pay miners or validators for their work.
📈 Why do gas fees change?
• 🕒 During peak hours (for example, in the evening or during NFT hype) — gas prices can "skyrocket"
• 🤖 If you do not set a limit — your wallet may automatically choose the expensive option
• ⚙️ Ethereum 2.0 and Rollups (like Arbitrum, Optimism) help reduce fees
🧠 How to save?
• ⏰ Make transactions during "quiet hours" — early in the morning or at night
• 🔍 Monitor gas prices on websites like etherscan.io/gastracker
• 🌉 Use Layer 2 solutions (Rollups) — there fees are several times lower!
🧩 Conclusion
Gas fee is like a toll for traveling in the blockchain city 🏙️
Sometimes there are traffic jams, sometimes it's free. The main thing is — plan ahead and don't overpay! 💡
