Binance Simple Earn is a platform that allows users to earn passive income by depositing their cryptocurrency holdings. It offers various investment options, including flexible and locked products, with different returns and timeframes. 

1. Flexible Products:

These offer immediate access to your funds, allowing you to redeem them at any time. 

Rewards are calculated based on a real-time APR that fluctuates with market conditions. 

You can subscribe to Flexible Products at any time and start earning rewards every minute. 

Assets subscribed to Flexible Products can be used as collateral for Binance Flexible Loans and in Binance Pay. 

2. Locked Products:

These offer higher yields in exchange for committing your assets for a fixed period. 

You earn rewards based on a predetermined APR, and early redemption incurs penalties. 

You can redeem your locked assets at any time before the redemption date, but you will forfeit any accrued rewards. 

Binance Simple Earn will redeem your assets to Flexible Products at the end of the subscription period.
