Crypto exchanges and their failures
In short
A friend of mine once kept a small pile of coins on an exchange, the way you might keep a few dollars in a coat pocket. You have probably done something close to that, or you know someone who has. Leaving crypto on an exchange feels easy, and it is, until the exchange stops working. When that happens, the coins are not sitting in a vault with your name on it. They may be a line in the exchange's own books, and you may be one of many people waiting in line. Bank deposits in the United States carry FDIC insurance, but the FDIC says on its own site that crypto is not covered. So the first step is to learn what you own and who holds the keys. The second is to keep only what you are ready to wait on. The third is to write down how to get your coins out.
The whole of it
What it is
I once watched a neighbor hand his house key to a man he barely knew, just so the fellow could water the plants. Nothing went wrong, but my neighbor slept a little worse that week. A crypto exchange is a bit like that. It is a company where you can buy, sell, and store digital coins. When you leave coins there, the company usually holds the keys that control them. Whoever holds the keys controls the coins. That is why people say "not your keys, not your coins."
If you are holding crypto on an exchange, you may own a claim against the company rather than the coins themselves. A claim is a promise to pay. It is only as good as the company that made it. Exchanges are not banks, and they do not follow the same rules. Some are regulated in some places for some activities. Many are not regulated the way a bank is. I mean no insult to the honest people who run them. Many work hard. But the structure matters more than good intentions.
How it works
Picture a coat check at a theater. You hand over your coat and get a ticket. The ticket says you own a coat. A well run coat check keeps every coat on a hook, matched to a ticket. A badly run one lends your coat to someone else for the night, hoping to have it back by closing. If everyone shows up at once, trouble starts.
Exchanges can work either way. Some keep customer coins separate and untouched. Others mix customer coins with company funds, lend them out, or use them for the company's own bets. Customers often cannot see which is happening. The terms of service you clicked past may say. Many people never read them, and I am no better. But those pages can spell out whether the company may lend your coins or treat them as its own.
When a lot of customers ask for their coins at once, a shaky exchange can run short. This is called a run. Withdrawals get paused. A notice goes up about "technical issues." Then comes a bankruptcy filing. In a bankruptcy, customers are often treated as creditors, which means people the company owes money. Creditors line up behind others and wait for a court to sort it out. That can take years. Often, they get back only part of what they were owed, and sometimes it is paid in dollars valued as of the filing day, not in coins.
I should say this gently: it has happened before. The collapse of FTX in 2022 is the best known case, and the bankruptcy proceedings have been public. Mt. Gox, an early exchange, failed in 2014 and left customers waiting for years. Court filings in each case are the place to learn what customers were actually owed. Pay attention to those records over any rumor.
The numbers, and where to find yours
Let me be plain about what I can and cannot give you. The rules around reporting and taxes on crypto change by year, so I will not write a number here that may be stale. The IRS has said on its website that digital assets are treated as property for tax purposes, and it asks about them on the front of Form 1040. If you sell, trade, or spend coins, you may owe tax on the gain. If an exchange fails and you lose coins, the tax treatment of that loss is a question for a tax professional and the current IRS guidance. Look up the IRS page on digital assets to see what applies this year.
For account protection, the two figures worth finding are these. First, the insurance level on a bank account, which the FDIC sets and posts at fdic.gov as the current figure, which the official source publishes each year. That covers bank deposits, not crypto. Second, if your exchange also holds cash for you, ask whether that cash sits at an insured bank and in whose name. Your own account will show your balances. Your exchange's terms page will say how it treats your assets. Look for words like "custody," "segregated," and "rehypothecation." That last word means lending out customer assets again. If you cannot find these words, send the company a message and ask.
A worked example
Let me tell you about a woman I will call Marta. She had saved 20,000 dollars and put 8,000 dollars of it into coins on one exchange. The other 12,000 dollars stayed in her bank. She figured the exchange was safe because the app looked polished.
Then the exchange paused withdrawals. A few months later, it filed for bankruptcy. Suppose the court found that customers would get back 40 percent of what they were owed. We can check the math. Her claim was 8,000 dollars. Forty percent of 8,000 is 8,000 times 0.40, which equals 3,200 dollars. She would lose 8,000 minus 3,200, or 4,800 dollars.
Now look at her whole savings. She started with 20,000 dollars. After the loss, she held 12,000 plus 3,200, which is 15,200 dollars. That is a drop of 4,800 out of 20,000, or 24 percent of her savings. The 40 percent figure is only for the sake of the example. Real recoveries vary, and they come after long waits.
Here is the part that stings. Marta did nothing foolish by her own lights. She trusted a nice looking app. If she had moved her coins to a wallet she controlled, her coins would have stayed hers. The wallet carries its own risks, like losing the keys. But it is a different risk, and she would have chosen it with open eyes.
Where it goes wrong
I have noticed that people lose coins in a handful of ordinary ways. The first is treating an exchange like a bank. It is not one. The second is chasing high interest offers. When a company pays you a rate that sounds too good, ask where the money comes from. Often it comes from lending your coins to others, and that lending is where the danger sits.
The third is skipping the fine print. The terms of service may let the company use your coins. The fourth is putting everything in one place. A single failure then reaches your whole stash. The fifth is waiting too long to act. Withdrawal pauses can start without warning, and once they start, you cannot get out.
There is a sixth, and it is quieter. People take on a false calm from a famous name or a big advertising budget. Size is no proof of safety. Plenty of large companies have failed.
Also keep your records. Download your transaction history now and then. If an exchange fails, the court will want proof of what you held. Without records, your claim gets harder to make. Save the statements and the dates. It is dull work. It pays off on the day you need it.
Questions to answer before you leave this page
Do you know who holds the keys to the coins you own, and have you read what your exchange's terms say about lending or using your assets? If the exchange paused withdrawals tomorrow, how much of your savings would be stuck, and could you live with that? Have you written down the steps to move your coins out, and have you tried a small test first? Do you keep your records somewhere safe, so you could prove what you held? And when an offer promises a rate that seems too good, have you asked where the money truly comes from?
