Why are crypto prices so volatile?

Supply and demand

The price of a cryptocurrency is simply the last price a buyer and a seller agreed on. If more people want to buy than sell, the price rises. If more want to sell than buy, it falls.

With shares, you can look at a company's profits and dividends to judge what a share should be worth. Bitcoin pays no profits or dividends. People value it for other reasons, such as its fixed supply and the fact that no single party controls it, and those are harder to put a number on. Without a simple formula, the price can travel further in both directions. Read more in Why does Bitcoin have value?

Supply is also rigid. Bitcoin's issuance is fixed and doesn't increase when demand shoots up. So changes in demand show up directly in the price.

A young and small market

Bitcoin has only existed since 2009. Stock and gold markets have far longer histories and are many times larger:

The gold figure is from the World Gold Council and the share figure from SIFMA, the US securities industry association.

In a small market, it takes less money to move the price. Bitcoin.org makes exactly this point: because the market is still small, it doesn't take large sums to push the price up or down. Smaller cryptocurrencies are even more sensitive than bitcoin and usually swing even more.

News and emotions

The crypto market reacts quickly and sharply to news. That might be new regulation, tariffs, interest rate decisions, hacks at crypto exchangesCrypto exchangeA company or platform where you buy, sell and swap crypto, for example with krónur. or comments by well-known people.

Emotions play a big part. When the price rises, FOMOFOMOThe fear of missing out, which pushes people to buy in a hurry when prices rise fast, often close to the top. (fear of missing out) sets in. More people buy and the price rises further. When the price falls, FUDFUDFear, uncertainty and doubt: negative news or rumours, true or not, that make people want to sell. (fear, uncertainty and doubt) spreads and people sell in a panic. That is how long stretches of big rises, bull marketsBull marketA long period when market prices mostly rise and investors are optimistic., and big falls, bear marketsBear marketA long period when market prices mostly fall and investors are pessimistic., come about.

Two examples from Bitcoin's history:

• 12 March 2020. As the pandemic was taking hold, the price of bitcoin fell 37% in a single day.
• November 2021 to November 2022. The price fell from about US$67,500 to about US$15,800. That is a drop of more than 75%.

The swings go both ways. In 2023, the price of bitcoin more than doubled.

Liquidity and whales

LiquidityLiquidityHow easily an asset can be bought or sold quickly at a fair price, without the trade moving the price much. describes how easily you can buy or sell without moving the price much. In a liquid market, there are always plenty of buyers and sellers waiting.

Many cryptocurrencies have little liquidity. A single large sell order can then push the price down a long way, because there aren't enough buyers at the current price. Liquidity is also often thinner at night and at weekends.

Large holders of crypto are called whalesWhaleSomeone who holds so much of a particular coin that their buying or selling can move the price.. When a whale sells a large amount at once, the price can drop fast, especially for smaller coins. Every transaction is visible on the BlockchainBlockchainA public ledger where transactions are grouped into blocks, each linked to the one before, so past records can't be altered without it showing., so even a large transfer between wallets can make the market nervous. With some cryptocurrencies, a small group holds a large share of the supply. See What is market capitalisation?

Leverage and liquidations

Many foreign crypto exchanges offer trading with LeverageLeverageTrading with borrowed money, which multiplies both gains and losses and can wipe out your whole stake in a short time.. People borrow money to take positions many times larger than their own funds.

An example: you deposit ISK 100,000 and open a position worth ISK 1,000,000 with tenfold leverage. If the price rises 10%, you have doubled your money. But if it falls 10%, all your money is gone. The exchange then closes the position automatically and sells. This is called a liquidationLiquidationWhen a loan or leveraged position is closed automatically because the collateral or margin no longer covers the debt..

Forced selling like this can set off a chain reaction. The sales push the price down, which triggers more liquidations, which push the price down further. That is what happened on 10 October 2025, after the US President announced new tariffs on China. Leveraged positions worth about US$19 billion were liquidated within 24 hours. The price of bitcoin fell by more than 10% within hours, and some smaller cryptocurrencies fell much further.

The market never closes

The Iceland stock exchange is open on weekdays. The crypto market is open around the clock, every day of the year.

Big price moves can therefore happen while you are asleep or on holiday. Stock exchanges can halt trading temporarily when prices move very sharply. Crypto markets generally have no such safety valves.

How to live with the volatility

The swings won't go away. These are not investment advice, but approaches many people use to make them easier to live with:

• Think long term. In the short run, prices are driven largely by chance and emotion. Many people who own crypto see it as a holding for years. Money you will need in the next few months doesn't belong in crypto.
• Only put in what you can afford to lose. The European supervisory authorities ESMA, EBA and EIOPA warn that you can lose a lot, or even all, of the money you put into crypto.
• Spread your purchases over time. Dollar-cost averagingDollar-cost averaging (DCA)Buying the same amount at regular intervals, for example monthly, instead of investing everything at once. means buying for the same amount at regular intervals, for example monthly. You buy more when the price is low and less when it is high. It reduces the risk of buying everything at the worst moment, but it doesn't guarantee a profit. See What is dollar-cost averaging?
• Avoid leverage. Leveraged trading can turn an ordinary swing into a total loss.
• Spread your risk. DiversificationDiversificationSpreading your money across different assets so that a fall in one of them has less effect on the whole. means not putting all your eggs in one basket.
• Don't watch the price every minute. Constant checking encourages snap decisions. Decide in advance what you plan to do and stick to it.

Closing thoughts

Crypto prices swing a lot. The market is young and small, there is no simple formula for what a coin should cost, and news, emotions and leverage amplify every move. And the market never closes.

The swings go both ways, and they are part of owning crypto. Learn about the risks before you buy.
