Founded in 2017, Poolin grew to become one of the world's largest cryptocurrency mining pools, particularly for Bitcoin and other Proof-of-Work (PoW) coins. The company provides a technical infrastructure that enables individual and large-scale miners to pool their hash power, stabilizing their income by earning fractional rewards consistently rather than facing the high variance of solo mining. In addition to its core mining pool service, Poolin expanded to offer a crypto wallet and other financial services. In September 2022, the company faced a severe liquidity crisis, forcing it to suspend withdrawals from its wallet service and later issue IOU tokens to affected users as part of a restructuring plan.
