You bought Bitcoin three years ago at $10,000. Today it is worth $85,000. Congratulations—you have a $75,000 unrealized gain.
Now you need $50,000 in cash. Maybe it is for a home renovation, a business investment, an emergency expense, or simply to diversify into other assets. If you sell $50,000 worth of BTC, here is what happens:
- Taxable gain: Roughly $44,118 (proportional gain on the BTC sold).
- Federal long-term capital gains tax (20%): $8,824.
- Net Investment Income Tax (3.8%): $1,676.
- State capital gains tax (5-13% depending on state): $2,206-$5,735.
- Total tax bill: Approximately $12,706 to $16,235.
That is $12,000-$16,000 gone—not to vendors, not to investments, not to your family. Gone to taxes. And that is just the federal picture in the US; high-tax states make it worse.
But there is an alternative that the wealthy have used for generations with their stock portfolios, real estate, and art collections: borrow against the asset instead of selling it.
Borrowing against Bitcoin is not a taxable event in most jurisdictions. And Borrow by Sats Terminal makes it easy to compare rates and find the most cost-effective way to access your Bitcoin's value without triggering a single dollar in capital gains tax.
Tax authorities generally define a "taxable event" as a disposition of property—a sale, exchange, or transfer of ownership. When you sell Bitcoin:
- You dispose of the asset.
- You realize the gain (difference between sale price and cost basis).
- That realized gain is taxable income.
When you borrow against Bitcoin:
- You retain ownership of the asset.
- No sale or exchange occurs.
- No gain is "realized"—the BTC sits in a smart contract as collateral, still your property.
- The loan proceeds are not income—they are borrowed funds that must be repaid.
This distinction is the foundation of a strategy used by the ultra-wealthy for decades. Jeff Bezos, Elon Musk, and other billionaires famously borrow against their stock holdings to fund their lifestyles and investments—precisely because borrowing is not a taxable event. Bitcoin now gives everyday investors access to the same strategy.
Traditional wealth management has a well-known framework:
- Buy appreciating assets (stocks, real estate).
- Borrow against those assets for liquidity instead of selling.
- Die (or hold until a stepped-up basis event resets the cost basis).
For Bitcoin holders, the adapted strategy is:
- Buy and Hold BTC for long-term appreciation.
- Borrow stablecoins against BTC when you need liquidity.
- Repay the loan from income, other sources, or by waiting for BTC to appreciate further and unwinding a small portion at a more tax-efficient time.
The critical advantage: at no point do you sell your Bitcoin and at no point do you owe capital gains tax.
How much cash do you need? Be specific. Over-borrowing increases cost and risk for no benefit.
Visit borrow.satsterminal.com and enter your desired borrow amount. The platform aggregates rates from DeFi protocols (Aave, Morpho, Compound) and CeFi lenders, showing you the best options ranked by interest rate, LTV, and terms.
At a conservative 40-50% LTV:
- To borrow $50,000 at 50% LTV, you need $100,000 in BTC collateral (~1.18 BTC at $85,000).
- At 40% LTV, you need $125,000 (~1.47 BTC).
Connect your self-custodial wallet to the chosen protocol through Borrow's interface. Deposit your BTC (as wBTC, cbBTC, or BTCB). Your keys remain your keys on DeFi protocols.
Execute the borrow transaction. USDC, USDT, or DAI arrives in your wallet within minutes. Convert to fiat or use directly.
Spend, invest, or deploy the borrowed capital. None of this triggers a taxable event related to your Bitcoin.
When you are ready, repay the stablecoins plus accrued interest. Your BTC collateral is returned. Again—no taxable event.
Let us compare the two approaches side by side for someone needing $50,000 in liquidity.
| Item | Amount |
|---|
| BTC cost basis | $10,000 per BTC |
| Current BTC price | $85,000 |
| BTC sold to get $50,000 | 0.588 BTC |
| Capital gain realized | $44,118 |
| Federal LTCG tax (20%) | $8,824 |
| NIIT (3.8%) | $1,676 |
| State tax (est. 8%) | $3,529 |
| Total tax owed | $14,029 |
| Effective cost of accessing $50,000 | $14,029 (28.1% of amount accessed) |
| BTC remaining after sale | Reduced by 0.588 BTC permanently |
| Item | Amount |
|---|
| BTC deposited as collateral | 1.3 BTC ($110,500) |
| LTV ratio | 45.2% |
| Borrow amount | $50,000 |
| Annual interest rate | 3.5% |
| Loan duration | 6 months |
| Total interest paid | $875 |
| Effective cost of accessing $50,000 | $875 (1.75% of amount accessed) |
| BTC remaining after repayment | All BTC returned, unchanged |
- Selling costs $14,029 (and you permanently lose 0.588 BTC).
- Borrowing costs $875 (and you keep all your BTC).
Savings from borrowing: $13,154—or roughly a 93.8% reduction in the cost of accessing liquidity.
And if BTC appreciates during those 6 months? The sold BTC buyer misses that upside entirely. The borrower captures all of it.
If your loan health deteriorates and the protocol liquidates your collateral, that forced sale is likely a taxable disposition. This is why conservative LTV management is not just a financial safety measure—it is a tax strategy.
Practical protection:
- Keep LTV at or below 45%.
- Monitor your health factor regularly.
- Set alerts for BTC price drops that would require action.
- Have a plan to add collateral or partially repay if BTC drops 30%+.
Crypto tax treatment is an evolving area. While borrowing against crypto is currently not a taxable event in most jurisdictions, this could change. Stay informed and maintain records of all borrowing transactions.
Converting native BTC to wrapped versions (wBTC, cbBTC) for use in DeFi could be considered a taxable exchange in some interpretations. The IRS and other tax authorities have not provided definitive guidance on all wrapping scenarios. Consult a crypto-specialized tax advisor.
Some US states have no capital gains tax (e.g., Florida, Texas, Wyoming). If you are in a zero-state-tax jurisdiction, the tax savings from borrowing versus selling are reduced (but still significant at the federal level). If you are in a high-tax state like California or New York, the savings are even more dramatic.
If your cost basis is far below today's price, every sale triggers substantial taxes. Borrowing lets you access the value your Bitcoin has generated without paying the tax cost of that appreciation.
If your income already puts you in the highest capital gains bracket (20% + 3.8% NIIT + state), the tax on selling BTC is maximized. Borrowing is proportionally more valuable.
If you have held BTC for just under a year, selling now means short-term capital gains taxed at your ordinary income rate (potentially 37% + NIIT + state). Borrowing to bridge the gap until you hit the one-year mark, then evaluating your options, can save thousands.
If you need cash for a defined period (home down payment, business expense, emergency) and plan to "refill" from other income sources, borrowing is almost always cheaper than selling and rebuying.
Both DeFi and CeFi options are available through Borrow by Sats Terminal:
| Factor | DeFi | CeFi |
|---|
| Tax reporting | Self-managed | May issue 1099s |
| Custody | Self-custody (no counterparty risk) | Custodial (counterparty risk) |
| Audit trail | Full on-chain transparency | Provider records |
| Liquidation risk | Automatic, algorithmic | May offer grace periods |
| Privacy | High (no KYC) | Lower (KYC required) |
For tax purposes, both approaches maintain the core benefit: borrowing is not a taxable event. The choice depends on your preference for custody, privacy, and reporting convenience.
Every dollar you pay in unnecessary capital gains tax is a dollar that could have stayed invested and compounding. If you hold appreciated Bitcoin and need liquidity:
- Visit borrow.satsterminal.com to compare borrowing options.
- Calculate the tax you would owe from selling versus the interest cost of borrowing.
- Borrow against your BTC at rates as low as 2-4% APR.
- Keep every satoshi and every dollar of unrealized gains intact.
