There are several ways to earn free Bitcoin Cash (BCH) online. Bitcoin Cash faucets allow users to claim small amounts of BCH by completing simple tasks or solving captchas. Crypto airdrops distribute BCH to participants who meet certain criteria, such as owning specific cryptocurrencies or participating in promotional events. Additionally, some websites and apps offer BCH rewards for activities like taking surveys, watching videos, or shopping through their affiliate links. While these methods typically provide small earnings, they offer a convenient way to start collecting Bitcoin Cash without any upfront investment.
