Bitcoin Faucets are sites that provide a small amount of Bitcoins (aka Satoshis) every few minutes for free while making money from displaying ads to these users. As these sites are giving away free money, they have become extremely popular.
Most online faucets either payout directly to your Bitcoin wallet or use a 3rd party micropayment wallet like CoinPot, Coinbase, Blockchain.com, etc
Mentioned below are a few critical parameters to look out for in a Bitcoin Faucet:
Number of Satoshis we get or we can earn per claim?
Interval time or How long one needs to wait between claims.
What is the minimum amount you can withdraw from your balance.
How will you receive the amount you withdrew? Ie Direct Bank transfer, Bitcoin wallet, etc.
What’s the fee you get for referring new users to the faucet?
