One of the oddities of crypto is that its market does not have opening and closing time. In regular stock markets, there is a schedule of when to open and close the market and weekends are considered non-trading days.
It has been made possible by the fact that crypto markets use online platforms for trades and decentralized finance uses blockchain platforms. The decentralized markets can work using smart contracts and liquidity pools instead of working from one particular building and one fixed schedule of trading. Ethereum describes the operation of such markets 24/7, every day of the year.
I think this feature will change the atmosphere of the market entirely since it is impossible to say whether the market closes or becomes less active. Something may happen during a Saturday morning or even during night when most markets close.
Such constant availability was one of the oddest features that crypto has introduced to the finance industry.
However, constant availability is not necessarily better. First, it implies a lack of a natural break between one day and another. Prices may continue to be volatile while everyone sleeps, and any news might influence the market anytime.
Additionally, crypto markets introduced several new financial products that are designed in such a way to fit the continuous availability nature. For instance, perpetual futures do not have an expiration date, and nowadays, several crypto derivatives markets provide 24/7 access.
However, the idea is even broader than just trading. Blockchain-based financial services can function 24/7 since there is no business day schedule for blockchains or smart contracts.
In my opinion, this is one of the most interesting aspects of crypto markets. Not only it brought digital assets to the world, but it brought new financial systems as well. With crypto markets, the idea of the market became different. There is no longer a notion of opening and closing the market, it is continuously operating.
