Your crypto doesn't have to sit idle and gather virtual dust. It can efficiently contribute to your passive income through interest-bearing accounts.

How much you earn depends on several factors, like the platform you choose, the type and amount of crypto, the interest type, the timeframe, and additional bonuses and rewards.

Rates often vary between platforms due to differences in their business models, risk management strategies, etc. 

This underlines the importance of understanding the fundamental factors driving returns rather than focusing solely on interest rates.

There's also a variation offered in the rates across different assets due to demand-supply dynamics, market volatility, etc.

Typically, higher rates are associated with coins that carry a higher level of risk, and vice versa.

When it comes to interest types, there are simple and compound interest. 

The former takes into account only the principal amount, while the latter incorporates both the principal and the compound interest over time.

Typically, interest rates on crypto platforms can be further increased by taking advantage of loyalty programs and limited-time offers.
