What is a faucet?
Faucets are a reward system, in the form of a website or app, that dispenses rewards for visitors to claim in exchange for completing a captcha or task as described by the website. There are also faucets that dispense alternative cryptocurrencies.
How they work
Rewards are dispensed at various predetermined intervals of time. Faucets usually give fractions of a coin, but the amount will typically fluctuate according to the value of the coin. To reduce mining fees, faucets normally save up these small individual payments in their own ledgers, which then add up to make a larger payment that is sent to a user’s address.
