crypto lending and borrowing platforms

In short

A friend of mine once told me he had found a way to earn interest on his coins without selling a single one. I understood why that sounded good to him. You have probably heard a pitch like it. A crypto lending platform lets a person lend digital coins to others and earn interest. It also lets a person borrow cash by putting coins up as security. Before you touch one, learn who actually holds your coins once you hand them over. Learn what price drop would force a sale of your collateral, which is the property you pledge to back a loan. Read the terms page and the withdrawal rules first. Write down every fee in dollars, not just percents. Then decide with a clear head, since the platform makes money whether or not you do.

The whole of it

What it is

I once watched a neighbor hand his tractor keys to a stranger because the stranger offered to pay him rent on it. It worked out, but only because the stranger was honest and careful. A crypto lending platform asks something like that of you. It is a company or a software protocol that connects people who want to lend coins with people who want to borrow them.

There are two broad kinds. The first is a centralized platform, which is a regular company. You send it your coins, and it lends them out and pays you a share of the interest. The second is a decentralized platform, which runs on code posted to a blockchain, the shared public record that tracks who owns which coins. There, no company stands in the middle, and automated rules called smart contracts match lenders and borrowers.

A borrower on either kind usually puts up more value than the loan is worth. That extra cushion is called overcollateralization. It exists because the platform cannot chase down an anonymous borrower the way a bank chases a homeowner.

How it works

If you are thinking about lending, the picture is simple. You deposit coins. The platform lends them out. The borrower pays interest, and the platform keeps a cut and passes the rest to you. The rate you see is usually quoted as an annual percent. It can change from day to day, and it is often not promised.

If you are thinking about borrowing, the picture has one more moving part. You pledge coins as collateral and receive a loan in cash or in another coin. The platform sets a loan to value ratio, which is the loan amount divided by the collateral value. If your coins fall in price, that ratio climbs. At a set point, the platform may sell some or all of your collateral to cover the loan. That forced sale is called liquidation, and it can happen fast, sometimes while a person is asleep.

Here is the part that trips up careful folks. On many centralized platforms, the terms may let the company lend out, pledge, or mix your coins with its own. That means the borrower is not the only one who has to repay. The platform itself has to hand your coins back. If it cannot, you may stand in line with other creditors. Several well known platforms froze withdrawals and filed for bankruptcy in 2022, and customers in those cases had to file claims in court.

Another thing worth knowing is that deposits at a crypto platform are not the same as deposits at a bank. The FDIC, the Federal Deposit Insurance Corporation, insures bank deposits, and it has published notices saying its insurance does not cover crypto assets or protect against the failure of a crypto company. You can read the FDIC's statements on its own website.

The numbers, and where to find yours

I am a plain man when it comes to figures, so let me name the ones worth hunting down. Look first for the advertised interest rate on lending and the borrowing rate on loans. Find the loan to value ratio at which the platform will warn you, and the higher one at which it will liquidate. Find any liquidation penalty, any withdrawal fee, and any minimum deposit.

Every one of those lives in the platform's terms of service, its rate page, or its help center. Do not trust a marketing banner. Open the actual terms and read the sections on custody, on rehypothecation (a long word for the platform reusing your coins), and on what happens if the company fails.

Taxes belong on your list too. The IRS treats digital assets as property. Its Notice 2014-21 laid out that basic rule. Form 1040 has carried questions about digital asset activity in recent years, but the exact wording has changed over time. Interest paid in coins may count as income when received, and selling or swapping coins can trigger a gain or a loss. The tax rules and the forms change, so check IRS.gov for the current version, and ask a tax professional about your own case. If the rules set a threshold or a rate, it will be on the IRS page, not in my head.

A worked example

Let me tell you about a woman named Dana. She holds coins worth $20,000 and wants cash for a home repair without selling. She finds a platform that will lend her up to 50 percent of her collateral value. She borrows $8,000 against her $20,000 in coins.

Her starting ratio is $8,000 divided by $20,000, which is 0.40, or 40 percent. The platform sets its liquidation point at 80 percent. So how far can her coins fall before trouble starts?

At 80 percent, her collateral would be worth $8,000 divided by 0.80, which is $10,000. That means her coins can drop from $20,000 to $10,000 before liquidation. A fall of $10,000 on $20,000 is a 50 percent drop. Coins have swung that much in short stretches before, so it is no idle worry.

Now add the cost. Suppose the loan charges 9 percent a year. Interest on $8,000 at 9 percent is $8,000 times 0.09, which is $720 a year. Over six months she owes about $360. Say the platform also charges a 1 percent origination fee, which is a one time fee for making the loan. That is $8,000 times 0.01, or $80. So her first six months cost about $360 plus $80, which is $440 in total, before any change in the price of her coins.

Dana should also ask what happens at the 80 percent line. If liquidation carries a 5 percent penalty and the platform sells $10,000 of collateral to cover an $8,000 loan, the penalty is $10,000 times 0.05, which is $500. That is a real cost, and it arrives at the worst possible moment. Dana is not foolish for borrowing. She just needs to see the whole bill before she signs.

Where it goes wrong

I have noticed that trouble in money rarely announces itself. It tends to arrive quietly, wearing a friendly face. With crypto lending, a few kinds of trouble come up again and again.

The first is platform failure. A company can lose money on its own bets or on loans that go bad. If it freezes withdrawals, a depositor cannot simply pull coins out. The second is a smart contract bug. On a decentralized platform, a flaw in the code can let an attacker drain funds, and there may be no customer service line to call.

The third is a price crash. A borrower's collateral can lose value quickly, and automatic liquidation does not wait for a phone call. The fourth is a high rate that hides a high risk. A rate far above what banks pay is usually paying you for something. Ask what.

The fifth is plain confusion over terms. Rates change, terms get updated, and a platform may restrict withdrawals in some places or at some times. Scams also dress up as lending platforms. The Federal Trade Commission and the Securities and Exchange Commission both publish warnings about crypto fraud and about investment products that promise steady returns. Reading those warnings costs nothing. Check them before you send anything anywhere.

Questions to answer before you leave this page

Do you know whether the platform holds your coins in its own name, and what its terms say about lending them out again? Can you find the exact rate, every fee, and the liquidation point written in dollars for your own loan or deposit? If your collateral lost half its value this week, could you add more coins or repay in time, and what would that cost you? Have you read what happens to customers if the company fails, and where claims would be filed? Do you know how the IRS treats the interest you earn or the coins you sell, and who will help you report it correctly? And finally, if the answer to any of these is still a shrug, are you willing to wait until it is not?
