Selling crypto converts it to cash, ends your market exposure, and triggers capital gains tax on any appreciation — up to 20% federal long-term plus a possible 3.8% surtax. Borrowing against it produces the same cash while keeping ownership and generally deferring taxes, at the cost of interest and liquidation risk. This is educational content, not personalized financial or tax advice; confirm your situation with a licensed professional.
Picture the decision most long-term holders eventually face: $100,000 of Bitcoin, bought years ago for $40,000, and a real need for $35,000 in cash — a renovation, a tax bill, a business.
If you sell $35,000 of BTC: roughly 60% of what you sell is gain (your cost basis is 40% of current value). About $21,000 of the sale is taxable appreciation. At the 15% long-term rate that's ~$3,150 in federal tax; at 20% plus the 3.8% surtax it approaches $5,000. You also no longer own that BTC — if it doubles over the next three years, the sold portion's upside is gone permanently.
If you borrow $35,000 against the full $100,000: you owe no tax today, you still own all the BTC, and you pay floating interest on the loan. If the interest rate averages, say, 5%, the loan costs ~$1,750 a year while it's open. What you've taken on instead of taxes is risk: if BTC crashes far enough, the position can be liquidated — which would itself be a taxable sale at the worst possible moment.
Numbers above are illustrative, not projections — rates, prices, and your basis change the math. But the structure of the trade-off doesn't change: selling trades future upside for certainty; borrowing trades certainty for continued ownership.
| Selling | Borrowing against | |
|---|---|---|
| Cash received | Sale proceeds minus tax | Full loan amount, no tax withheld |
| Taxes today | Capital gains on appreciation (0/15/20% federal + possible 3.8% NIIT + state) | Generally none — deferred, not eliminated |
| Ownership & upside | Ended on the sold amount | Retained on the full position |
| Ongoing cost | None | Floating interest while the loan is open |
| Ongoing risk | None | Liquidation if collateral falls; forced sale is taxable |
| Effort | One transaction, done | Position needs monitoring while open |
| Discipline required | None after the sale | Real — the credit line is always there, and re-borrowing temptation is the quiet failure mode |
An honest comparison page has to make the case for the other side, so here it is. Selling wins when:
Borrowing wins in the opposite conditions: long time horizon, large embedded gains, a cash need that's modest relative to the position (30–40% LTV or below), and the temperament to leave the rest of the credit line alone. The mechanics of setting that up are covered in the main borrowing guide, and the tax detail in crypto loans and capital gains tax.
Liquidation is the price of the borrowing path, and it deserves its own treatment — liquidation risk, explained with real numbers covers the mechanics, thresholds, and defenses. The one-paragraph version: at a conservative LTV, Bitcoin has to fall by more than half before a typical liquidation threshold is threatened; at an aggressive LTV, a routine correction can do it. The borrower chooses which of those positions to be in.
How OverseasDeFi thinks about this. We don't teach that borrowing is always right — we teach that most holders never learned it was an option, and made the sell decision by default. The comparison deserves twenty minutes of real math on your actual basis, your actual tax bracket, and your actual need. Sometimes the answer is sell. When it's borrow, the position should be sized so conservatively that a 2022-style drawdown is an inconvenience, not an emergency.
It depends on your time horizon and tax position. Borrowing suits long-term holders with meaningful unrealized gains who want cash without giving up the position. Selling suits anyone who needs certainty, holds a small position, or would be tempted to borrow aggressively. The honest answer is a math problem, not a slogan.
It defers it. A loan is generally not a taxable event, so no capital gains are due when you borrow — but the embedded gain remains in the asset and is realized whenever you eventually sell, or if your collateral is liquidated.
Floating interest on the borrowed amount — on major DeFi platforms, stablecoin borrow rates have typically run in the mid-single digits annually, moving with market demand. Compare that annual cost against the capital gains tax a sale would trigger today and the upside you'd forfeit.
When you need money with zero ongoing risk, when the position is small relative to the cash need, when your cost basis is high so the tax cost of selling is low, or when a loan would tempt you to borrow at an aggressive loan-to-value ratio. A closed position can't be liquidated.
