Alchemix is a self-repaying loan protocol. By depositing crypto, you can start earning ALCX tokens and participate in guiding the protocol towards profitability. The ALCX token in turn, allows you to either earn rewards or borrow against your collateral while continuing to earn rewards. These rewards accumulate and can be applied to paying back your loan. This unique functionality makes it so Alchemix can offer loans that automatically pay themselves back over time. By simply holding your collateral, Alchemix effectively pays itself back for lending you crypto that is backed by your own money. This can be useful for leverage trading with no risk of liquidation.
