Both let you borrow against Bitcoin without selling, but they are built differently. Coinbase's loan is a decentralized finance (DeFi) product with a Coinbase front end; CoinRabbit is a centralized lender (CeFi) built for speed and maximum leverage. The right one depends on what you value: the lowest floating rate, or fast funding with the highest loan-to-value in the market.
This is an independent comparison, not advice. Coinbase figures are a snapshot because its rate floats; CoinRabbit figures are verified weekly.

Coinbase data is a snapshot (its rate floats); CoinRabbit figures are verified weekly. Neither is a recommendation.
The core difference
CoinRabbit funds in about ten minutes, asks for minimal identity verification, and lets you borrow up to 90 percent of your collateral's value, holding the Bitcoin itself. Coinbase converts your Bitcoin to cbBTC, supplies it to a Morpho market on Base, and lends you USDC, with liquidation enforced automatically by code. One is a fast, high-leverage company product; the other is a protocol plus Coinbase's custody of the wrapped-Bitcoin backing. Our CeFi vs DeFi guide covers why that distinction drives everything else.
Where they differ
Rate. Coinbase is usually cheaper on the headline number (recently around 5 to 6 percent, variable, no ceiling) than CoinRabbit (from about 11.95 percent).
Max LTV. CoinRabbit allows up to 90 percent, the highest in our set; Coinbase runs around 75 percent and liquidates at about 86 percent. A higher loan-to-value means more cash per coin but a thinner buffer.
What you receive. CoinRabbit pays cash or a stablecoin; Coinbase pays USDC, which you convert yourself.
Custody. CoinRabbit holds collateral itself and does not name a third-party custodian. Coinbase locks cbBTC in the Morpho market (not re-lent there), with the underlying Bitcoin custodied by Coinbase. Read our rehypothecation explainer for why that matters.
Speed and checks. Both fund fast. CoinRabbit asks for minimal identity verification; Coinbase requires a Coinbase account.
Who picks which
Lean CoinRabbit if you need to borrow the most per coin, want funding in minutes, and prefer light identity checks. Lean Coinbase if you want the lowest available rate, you are comfortable holding USDC and managing automatic liquidation, and you already keep Bitcoin on Coinbase. Both leave a thin buffer at high LTV, so size your loan with room to spare.
Is Coinbase or CoinRabbit cheaper for a Bitcoin loan?
Coinbase usually has the lower headline rate (recently around 5 to 6 percent variable) versus CoinRabbit (around 11.95 percent and up). But Coinbase's rate floats with no ceiling, and CoinRabbit lets you borrow far more per coin (up to 90 percent loan-to-value) with no origination or liquidation fee. Compare the all-in cost and how much you need to borrow, not just the rate.
What is the main difference between Coinbase and CoinRabbit?
Coinbase's loan is a DeFi product: your Bitcoin becomes cbBTC in a Morpho market on Base and you receive USDC, with automatic on-chain liquidation. CoinRabbit is a centralized lender with very fast funding (about 10 minutes), minimal identity checks, and a high maximum loan-to-value, holding collateral itself.
Which is safer, Coinbase or CoinRabbit?
Different risks. CoinRabbit holds collateral itself and does not publicly name a third-party custodian, and a 90 percent loan-to-value leaves a thin buffer before liquidation. Coinbase removes single-company lending risk via Morpho but adds smart-contract and oracle risk plus reliance on Coinbase's custody of the Bitcoin backing cbBTC, and liquidates automatically with no grace period.
