If you're looking to unlock liquidity from your Bitcoin or Ethereum, you'll likely choose between two models: decentralized (DeFi) or centralized (CeFi) finance. They are fundamentally different in terms of how they work and the risks they carry.

This isn’t about which one is “better.” It’s about understanding how each works and which one aligns with your needs, risk level and level of experience.

Let’s dive in.

What is DeFi?

DeFi stands for decentralized finance. It’s a set of open protocols, mostly on Ethereum, that allow you to lend, borrow, trade or earn interest using smart contracts.

Smart contracts are programs that live on the blockchain and execute automatically when conditions are met. When you borrow using DeFi, you’re not filling out a form or talking to anyone. You’re interacting with code.

When you borrow on a DeFi protocol you deposit crypto into a smart contract as collateral. Based on predefined rules, the contract lets you borrow a stablecoin like USDC, USDT or another crypto. Your loan stays open as long as your collateral remains above a certain value.

No central authority. No gatekeepers. No need to ask permission. That’s the beauty of it.

But there’s a trade-off. With DeFi, you are the system administrator. You hold your own keys. You interact with complex user interfaces. You manage risk yourself. If the collateral ratio drops too low, the contract will liquidate your funds without warning. No appeals. No support to reach out to. No explanations. Just code executing.

This isn’t a bad thing. In fact, it’s one of the most powerful innovations in modern finance. But it’s not for everyone. And there’s plenty of examples of DeFi protocols being hacked in the past.

Why DeFi isn’t for Everyone

One major limitation of DeFi is Bitcoin support. Bitcoin cannot currently be lent against on DeFi protocols directly. Instead you have to convert your Bitcoin to something called wrapped Bitcoin (wBTC), or cbBTC (another form of wrapped BTC issued by Coinbase) or another form of a representation of Bitcoin on a DeFi, ERC-20, or other compatible blockchain. That means you have to trust the company issuing the wBTC to hold your real BTC and give you an ERC-20 compatible token in exchange.

This introduces counterparty risk. It also introduces tax complications. In many jurisdictions converting BTC to wBTC is considered a taxable event (you are in essence selling your BTC when you buy wBTC with it). You’ve sold one asset and acquired another. If your cost basis is low, that could mean a big tax bill. For many Bitcoin holders, that’s a dealbreaker.

The inner workings of DeFi lending protocols means that interest rates vary depending on supply and demand. This means that for a borrower, interest rates are not static and though they can fall to low single digits, they can also rise to +30% during market volatility.

In Summary:

Why DeFi is Good:

• Permissionless access: Anyone with internet access and crypto can lend, borrow, or trade without intermediaries.

• Self-custody: Users control their own funds through private keys.

• Automation: Smart contracts enforce terms instantly and transparently, reducing human error and overhead.

• Innovation: Enables composable financial products, open-source experimentation, and global access to capital.

• Interest rates: at times considerably lower than borrowing from centralized lenders.

Why DeFi is Risky or Limiting:

• User responsibility: You manage your own security, collateral, and risks—no customer support, no recourse.

• Liquidation risk: If your collateral value drops, your position can be liquidated automatically and irreversibly.

• Fees: Gas fees are usually exorbitantly high during moments of high market volatility, making the act of topping up collateral very pricey.

• Interest rates: highly variable, rising to as high as +30% during times of high market volatility.

• Complexity: Interfaces and processes can be unintuitive or intimidating for non-technical users.

• Hacks and bugs: Smart contracts can be exploited, with no centralized entity to restore lost funds.

• Bitcoin limitations: Native BTC isn’t supported directly—users must convert to wrapped BTC, introducing counterparty risk and often taxable events in some jurisdictions.

Bottom Line:

DeFi empowers users with control and access but demands a high degree of technical understanding, risk management, and comfort with irreversibility. It’s powerful but not always practical or safe for the average user.

What is CeFi?

CeFi, or centralized finance lending platforms offer an experience that is closer to what most people are used to. You sign up with a regulated platform such as APX Lending. You verify your identity and sign a loan agreement. You send your BTC or ETH collateral. The platform gives you a loan in fiat currency or a stablecoin.

CeFi platforms act as custodians. They hold your collateral in secure wallets, often with insurance, and they manage the loan process for you. You don’t have to wrap assets, or interact with code. You don’t have to understand smart contracts. And in many cases, you avoid triggering taxable events because you’re not swapping one asset for another when you take out a loan.

With a CeFi lender you are usually able to get locked rates that do not fluctuate with market volatility, providing for a more predictable and stable borrowing experience.

This model relies on trust. You’re trusting the platform to manage custody, execute liquidations fairly and comply with regulations. In return you get a more familiar experience. Some people are comfortable with that. Others aren’t. Both are valid. Working with regulated and insured platforms is prudent in making sure that your collateral remains safe and secure for the duration of your loan.

In summary:

Why CeFi is Good:

• User-friendly experience: Familiar, guided processes—sign up, verify identity, sign a loan agreement, deposit collateral, get loan.

• No code, no complexity: No smart contract interaction, no need to manage wallets or gas fees.

• No asset wrapping: You can use native BTC or ETH directly, avoiding wrapped tokens and potential tax events.

• Fixed interest rates: Borrowing rates are often locked in, offering predictability regardless of market conditions.

• Custodial support: regulated lending platforms use licensed and insured custodians, providing peace of mind.

Why CeFi Has Tradeoffs:

• Centralized trust model: You must trust the platform to safeguard your funds and act fairly—this introduces counterparty risk.

• Custodial dependence: You give up control of your private keys and depend on the platform for security and access.

• Less transparent: Unlike DeFi, inner operations may not be fully visible or auditable by the user.

• Limited composability: CeFi platforms are often closed systems, lacking the interoperability and innovation of DeFi protocols.

• Interest rates: there is a cost to running a centralized platform, so rates are usually higher than DeFi (though during volatile times DeFi rates can be multiple times higher than CeFi rates).

Bottom Line:

CeFi offers a safer, simpler, and more predictable experience for most users—especially those less technical or risk-averse. However, it comes with tradeoffs around control, transparency, and reliance on third-party trust. For many borrowers, especially those using BTC as collateral, CeFi is a more practical option.

Comparing the Two Models

Again, it’s not about which is better. It’s about tradeoffs.

If you’re a technical user who prefers full control, DeFi gives you the tools. But it expects you to understand how they work and to accept full responsibility if something goes wrong.

If you’re a long-term holder who values ease of use, clear terms and regulatory protections, CeFi might be a better choice. You give up some control but you get simplicity and structure.

Why This Matters

One of the most important things in the crypto industry is lack of user education. Before choosing a product or service, it’s important to understand not just how it works, but also the assumptions it’s built on and the responsibilities it places on the user.

With DeFi you are opting into an open, autonomous system. The rules are coded. If those rules don’t serve you in a specific situation, the consequences can be dire. There is no help desk. With CeFi you are relying on people, policies and legal agreements. Those can be slower or more rigid but they often come with real world protections and support.

Both have strengths and risks. The key is understanding the tradeoffs

Final Thoughts

This is not a winner-takes-all scenario. DeFi and CeFi are different tools for different jobs. They can coexist. They already do.

If you want maximum control and you are comfortable with the responsibility that comes with it, DeFi is for you. If you want a structured, regulated and secure way to access liquidity from your Bitcoin or Ethereum, with less tax consequences, CeFi is probably the better choice.
