Earn is a feature within BLOX that allows you to easily earn extra returns on your crypto. Once you activate Earn for an available coin, your crypto is lent out to carefully selected partners who use it to generate yield. You receive a portion of that yield as a reward. The rewards varies per coin and is automatically credited to your Vault every Monday.
The coins you activated for Earn remain fully available for trading. They are not locked, which means you stay flexible and can react to market movements or other opportunities. You always remain in control and can sell your crypto at any time.
Activating Earn is easy with the help of this FAQ page.
