Say you need $5,000 in the next two weeks. You’ve got it, sitting in Bitcoin — bought two years ago, up a lot since, and the plan was always to hold it long-term. Now there’s a real bill in front of you and two ways to cover it: sell some of the BTC, or borrow against it and keep the position. Most people default to selling because it’s the option they already understand. It’s also, more often than not, the more expensive one — just not in a way that shows up on the first receipt.

This isn’t a question with one universal answer. But it is a question worth actually running the numbers on, instead of just picking whichever option feels more familiar.

What Selling Actually Costs You

Selling looks simple: you convert crypto to cash, done. The cost that’s easy to miss is what happens *after* the sale, on two fronts.

First, you’ve realized a gain (assuming the coin is worth more than you paid for it), and in most jurisdictions that’s a taxable event the moment you sell — not when you eventually spend the cash. Depending on where you live and how long you held the asset, that can mean a meaningful chunk of the gain goes to a tax bill you weren’t necessarily planning for this month. Rules vary a lot by country, so this isn’t the place for specifics — talk to a tax advisor in your jurisdiction before assuming either option is automatically cleaner on this front. But it’s worth flagging clearly: selling triggers a taxable disposal in a lot of tax systems. Borrowing against the asset generally doesn’t, because you still own it.

Second, and this is the part people actually regret later: you’re out of the position. If Bitcoin doubles over the next year — and it has, more than once, in less time than that — you sold at the bottom of that move to cover a $5,000 bill. The opportunity cost doesn’t show up anywhere on a statement. It just quietly compounds in the background while you’ve moved on.

What Borrowing Against It Actually Costs You

The cost of a collateral loan is upfront and visible, which is honestly its main advantage: you know exactly what you’re paying before you commit to anything.

On LoanCryptoBank, the structure is straightforward. Deposit your BTC or ETH, and the platform values your loan at 50% of the current market value of what you’ve deposited — so $10,000 in crypto gets you a $5,000 loan, in USD, EUR, or UAH depending on what you need. Interest runs at 0.1% per day on the outstanding balance, calculated daily, not compounded into some opaque monthly figure you have to reverse-engineer. Minimum term is one week, and you can repay whenever you’re ready — there’s no penalty for paying early, and refinancing is an option if you want to extend rather than close out.

Run the actual math on that $5,000 example: over a 12-week loan, at 0.1% daily interest on the $5,000 balance, that’s roughly $420 in total interest if you hold the loan the full term (less if you repay sooner, since it’s daily, not front-loaded). Compare that to the tax bill on a comparable capital gain in a lot of jurisdictions — even at moderate gain levels and moderate rates, $420 is often the cheaper number, and that’s before you factor in what you’d have made if the crypto kept climbing while you still held it.

The one real risk on this side of the comparison: if the price of your collateral drops far enough, you’ll hit a margin call — a point where LoanCryptoBank sells the collateral on the open market to guarantee repayment of the loan. That’s not a penalty or a punishment, it’s just how a collateralized loan has to work; the lender needs the loan to stay backed by enough value to cover it. You get visibility into where that threshold sits before you ever deposit anything, and refinancing is available if you’d rather adjust terms than risk hitting it.

So Which One Actually Costs More?

It depends on three things, honestly, not one clean formula: how big your unrealized gain is (bigger gain, bigger potential tax hit from selling), how long you need the cash for (a short bridge favors borrowing — the interest cost stays small), and how confident you are that the asset keeps moving in a direction that makes holding worth it.

If you’re sitting on a large, long-held gain and only need cash for a few weeks, the math usually tilts hard toward borrowing — the interest is small, the tax event you’re avoiding could be substantial, and you keep the upside if the market keeps moving. If you’ve got a small or negative gain and need the cash for a long stretch, selling might genuinely be the simpler, cheaper call — there’s less tax exposure to protect against, and long-term interest on a big loan adds up.

The honest answer nobody likes hearing: run your own numbers before deciding either way. A rough calculation takes a few minutes and can save you from either an unnecessary tax bill or an unnecessary loan.
