How Does Lending Compound Interest Work? The Power of Daily Reinvestment
Lending interest settles daily, and once it reaches the minimum amount, it's automatically reinvested into new loans, creating daily compounding. This article explains in plain terms how compounding works, how it compares to simple interest, and why automatic reinvestment matters.
Lending compound interest means lending out the interest you receive each day, so the interest itself starts earning interest. On Bitfinex, interest is credited once a day; once it adds up to the minimum offer size (150 USD or equivalent), it can be offered again as new principal, letting your principal snowball (see Bitfinex's funding rules).
What does daily interest settlement mean?
The funds you lend out earn interest that settles daily and credits directly to your account — you don't have to wait until maturity to receive it all at once.
What is automatic reinvestment?
Once the interest credited each day accumulates to the exchange's minimum order amount, it's automatically re-listed as new principal for lending, letting your principal snowball over time. For how this happens automatically, see What Is an Auto-Lending Bot.
How much difference does compounding make versus simple interest?
Conceptually: with simple interest, the principal stays fixed and only it earns interest; with compound interest, the interest itself starts earning interest too. The longer the time frame and the higher the APY, the more pronounced the gap becomes. (Actual figures depend on the floating rate and are not guaranteed.)
How does automation keep compounding going?
Doing this manually means watching your account every day and gathering fractional interest until it hits the minimum before re-listing it — not easy. Bitfinex's Auto-renew can, based on your settings, automatically create new offers from available funds in your funding wallet; an automated lending tool goes further by adjusting offers to market rates and handling this every day.
