Forsage is a decentralized platform built on the Ethereum blockchain, that operates as a matrix program, where users can earn rewards through their referrals and their referrals' referrals. It is marketed as a way to earn passive income, but it has been criticized for being a pyramid scheme, as its structure is heavily reliant on the constant recruitment of new members to generate income for existing members. It is important to thoroughly research and understand the risks involved before participating in any investment opportunity, especially one that operates in a gray area like Forsage.
