Gavin Andresen initially loaded the faucet with 1,100 BTC from his own pocket. Early BTC miners and whales also donated BTC to it. The first Bitcoin Faucet allowed visitors to the website to receive 5 BTC (if available) by completing a captcha, inserting a BTC wallet address and then clicking on ‘Get Some’ (see screenshot below). The primary focus was to boost Bitcoin adoption. It disbursed about 19,700 BTC until it closed in 2012.
