Why do fees exist?
Bitcoin transaction fees are small amounts of Bitcoin you pay to send a transaction. They go to the miners who confirm transactions and add them to the blockchain. Without fees, there would be no incentive to process your transaction.
How are fees calculated?
Fees are based on data size, not the amount sent. A simple transaction might cost less, while one with many inputs or outputs could cost more. You can usually set the fee manually in your wallet.
Why do fees change?
Fees go up when the network is busy. If many people are sending Bitcoin at the same time, you’ll need to pay more to have your transaction processed quickly. When demand is low, fees drop.
Can I send Bitcoin for free?
Technically yes — some wallets let you set very low or even zero fees. But be aware: your transaction might never get confirmed. It’s safer to include a reasonable fee, especially if speed matters.
