⛽ Did a transaction fail and still incur a fee?

On Ethereum, fees are paid in $ETH , and gas measures the work required to execute an operation.

If a transaction is included in a block and fails during execution, its changes are reverted, but the work already done still has a cost. That’s why it can consume gas even if it doesn’t achieve what you intended.

Keep in mind the difference: if it’s rejected during validation, before being included in a block, it doesn’t consume gas.

The gas limit is the maximum amount of work allowed; it is not the fee price.

What did you find more confusing: gas, the limit, or the fee?

🪙 A coin priced in cents isn’t automatically a bargain.

Comparing $BTC and $ETH by their unit price can be misleading. To compare their size, the number of coins in circulation matters too.

Market capitalization = price × coins in circulation.

Hypothetical example:
• A: US$0.10 × 1 billion = US$100 million.
• B: US$10 × 1 million = US$10 million.

A costs less per unit, but has a higher market capitalization. That doesn’t prove it’s a better investment either: liquidity, utility, and future issuance also matter.

Also, market capitalization isn’t the same as the amount of money that has flowed into the project.

What did you look at first: price or market capitalization?

🔐 Three concepts to understand your wallet at $BTC

1️⃣ Public address: lets you receive funds. You can share it, although its activity can be viewed on the blockchain.

2️⃣ Private key: authorizes transactions. It must remain secret.

3️⃣ Recovery phrase: in wallets that use one, it lets you restore access. It should not be shared either.

There’s another important difference: with custodial wallets, a third party manages the keys; with non-custodial wallets, that responsibility is yours.

Which concept did you have the most questions about?
