Lightning Network is a payment network built on top of Bitcoin. It is designed for faster and cheaper small payments by using payment channels instead of putting every payment directly into a block.

What it is good for

Lightning can be useful for small purchases, creator payments, merchant payments and frequent transfers where on-chain fees would be too high.

Tradeoffs

Lightning has different operational risks than simple cold storage. Liquidity, channel management, backups and wallet type matter. Custodial Lightning wallets are easy to use but require trusting the provider.

Beginner approach

Start with a small amount and learn the difference between custodial and non-custodial Lightning wallets. Treat it like a spending wallet rather than a vault.

When on-chain is better

For long-term storage or larger transfers, an on-chain wallet with a secure backup is often more appropriate. For large balances, review cold wallet basics.
