What a crypto faucet is
Faucets began as a way to show new users how a coin works by giving them a tiny amount for free. Today they are funded by advertising: you see ads while you claim, the advertiser pays the site, and part of that money comes back to you as coins. That is why a faucet can be free and why each claim is small. A faucet is a good first step into crypto, and it needs nothing from you except a few seconds and a wallet.
