Bitcoin interest accounts: who pays the yield and who controls the coins?

A BTC interest account resembles a deposit only from a distance. Bitcoin itself produces no yield; the intermediary controlling the coins does.

The offer sounds familiar: transfer BTC to an account, choose a term and receive regular interest in bitcoin. It resembles a bank deposit, but the resemblance hides the most important distinction.

Bitcoin itself does not generate interest. Its protocol contains no deposit account, management company or mechanism that rewards an owner merely for holding coins. Whenever someone offers a yield on BTC, an intermediary has appeared between the owner and the network.

That intermediary’s activity creates the yield—and the additional risk.

Where the yield comes from

After BTC reaches an interest account, a platform may lend it, use it as collateral for other operations or deploy it through its own financial strategies. It keeps part of the resulting income and credits another part to the client.

Owner transfers BTC → platform uses the BTC → client receives part of the income.

The interest does not arise from storage. It compensates the owner for supplying capital to a platform and accepting its risks.

Why “deposit” can be a misleading word

The product may resemble a bank account in an app while operating under a very different legal structure.

Once BTC is sent to a platform-controlled wallet, the user no longer controls it with personal keys. The screen shows an account balance and a claim against the company for the return of an equivalent amount of BTC. Recovery now depends not only on the Bitcoin network, but also on the product terms, the company’s solvency, its security and its withdrawal rules.

Some venues say this explicitly. Binance Japan warns that Simple Earn is not a deposit or deposit-like product, is not covered by deposit insurance and may not be returned if the company fails.

This does not mean every such service must end in a loss. It means that risk has moved from self-custody into trust in a company.

What is currently offered

At the time of review, Nexo advertises up to 5.7% annual interest on BTC. The words “up to” matter. The highest rate depends on the term, loyalty level, the share of NEXO tokens in the portfolio and the reward option. Simply depositing BTC does not necessarily produce the headline rate.

Other exchanges offer flexible and fixed Earn products. Flexible products usually permit faster redemption, while fixed terms lock the coins for a set period. Rates can change, and early redemption may remove rewards already credited.

Products can disappear as well. Ledn ended its BTC and ETH Growth Accounts in 2025 to focus on bitcoin-backed loans. A product may not remain available for as long as its user intends to hold BTC.

A history that cannot be ignored

Celsius also offered interest and described its platform as a safe alternative to a bank. According to the U.S. Commodity Futures Trading Commission, it pooled customer assets and deployed them to generate revenue.

To support the promised rewards, Celsius used increasingly risky strategies, including uncollateralized loans. It later halted withdrawals and entered bankruptcy. In June 2026, the CFTC concluded its action against the company’s founder, who had previously received a twelve-year prison sentence.

The case does not prove that every interest platform is the same. It shows how difficult it can be for a client to see the actual risk behind a calm interface and regularly rising numbers.

While payments continue, the product looks simple. Its real structure becomes visible when many owners try to recover their BTC at the same time.

Check before transferring bitcoin

• Which legal entity receives the BTC, and where is it registered?
• Are client assets separated from the company’s own property?
• Can the platform make uncollateralized loans with BTC?
• Are both reserves and liabilities disclosed?
• Can BTC be withdrawn at any time or only at the end of a term?
• Under what conditions may withdrawals be suspended?
• Is interest paid in BTC, or does the best rate require another token?
• How much of the advertised rate is available without extra conditions?
• What do the terms say about insolvency, theft and regulatory change?

If those questions do not have clear answers, the yield cannot be evaluated honestly.

Do not confuse yield with a guarantee

A BTC yield is appealing because the number of coins can rise without selling the original asset. A few percent in rewards, however, does not remove the possibility of losing much more—including the entire amount transferred.

The higher the promised rate, the more important it is to understand what the platform does with the BTC and what risk that activity creates.

A self-custody wallet pays no interest but, when used correctly, leaves control with the owner. An interest account adds yield by giving part of that control to an intermediary. This is not a choice between “profit” and “doing nothing.” It is a choice between different forms of responsibility.

The central lesson

Bitcoin interest accounts exist as commercial company products, not as a feature of Bitcoin itself.

Coins do not multiply by sitting in an account. To pay interest, someone must use them and take financial risk. The essential questions are who receives the income, who controls the keys and who carries the loss when the calculation fails.

A transfer of BTC for yield should therefore begin not with “how much will I earn?” but with a different question:

Who am I giving my bitcoin to—and what would have to happen for me not to get it back?

Yield does not emerge from the Bitcoin protocol. It appears when someone begins using the BTC entrusted to them.
