Why Do Crypto Markets Never Close?

Crypto markets never close because there is nothing to close. No exchange building, no opening bell, no country whose working day sets the hours. Blockchains keep producing blocks every minute of every day, and the venues that trade on top of them run continuously too.
No building, no bell
A stock exchange is an institution with staff, a jurisdiction and a timetable, so it opens, closes and takes holidays. Bitcoin is software running on thousands of computers around the world, and it produces a new block roughly every ten minutes whether it is Sunday or not. Ethereum produces one about every twelve seconds. Exchanges such as Binance and Coinbase match orders around the clock, and a decentralised exchange like Uniswap is only code. Code has no opening hours.
What that changes for prices
On a stock market, news that breaks on Saturday gets priced in at Monday's open, often as a gap where the price simply restarts somewhere else. Crypto has no gaps, because it never stopped. News is absorbed as it lands, at three in the morning if that is when it lands. The trade-off for that continuity is a market that can move sharply while you are asleep.
Why weekends feel violent
Fewer people trade at weekends and overnight, so less money rests in the order books, the lists of waiting buy and sell offers. Thinner books mean a given order pushes the price further. That is why a weekend move often looks dramatic next to the same order size on a Tuesday afternoon. Nothing is broken when it happens. There is just less on the other side.
How to live with it
- Do not plan to watch the market. You cannot watch all of it, and trying is how people end up deciding things at four in the morning.
- Learn limit orders, an instruction to buy or sell only at a price you choose, so an overnight move does not need you awake to handle it.
- Expect wider spreads and bigger swings at weekends, and keep whatever you are testing small.
