What Is a Market Crash in Crypto?

A crash is a sudden, steep fall in prices — a big drop over hours or days, rather than the slow grind of a bear market. Crypto has had several. On 12 March 2020, as the pandemic hit every market at once, bitcoin lost roughly half its value in a single day. The word describes the speed, not the size: a crash can start a long decline or be over by the weekend.

Why can crypto fall so fast?

Mostly because of borrowed money. Many traders buy with credit from an exchange, and that credit comes with a condition: if the price drops past a set point, the exchange sells their position automatically to protect itself. Those forced sales push the price down further, which triggers the next set, and so on down the line. It is a crowd leaving a room through one door — each person is being sensible, and together they make it far worse. Crypto markets never close, so this can run at three in the morning, when fewer buyers are around to absorb it.

What did the big crashes have in common?

Something broke that people had assumed was solid. In May 2022 the Terra stablecoin, which was supposed to hold at one dollar, lost its peg and fell to nearly nothing within days, taking tens of billions with it. That November the exchange FTX collapsed and customers discovered they could not withdraw their own coins. In both cases the price drop was the visible part; the real damage was that money people believed they owned was simply gone.

What actually protects you?

Not clever timing. The risk that ruins beginners is rarely the price — it is where the coins were sitting. Coins on an exchange are a promise from a company; coins in a wallet whose keys you hold are yours, and a company failing cannot touch them. So keep long-term holdings off exchanges, ideally on a hardware wallet. Do not borrow to buy, since leverage is what turns a bad day into a total loss. And treat a stablecoin as a company's promise rather than a law of nature — the ones that broke all looked fine right up until they did not.

One practical thing to do today, while nothing is happening: check that you could actually move your coins off every platform holding them, and that you still have your seed phrase written down somewhere safe. Withdrawals get suspended during a crash, and that is the wrong moment to find out.
