Assalamu Alaikum
How are you all? Alhamdulillah I am fine. I hope you are well too. Bitcoin is a digital currency. So you can understand that different digital devices have to be used for this. But Bitcoin's blockchain also needs to be updated over time. Let me give a simple example. We all run YouTube more or less. As we saw YouTube 3-4 years ago, it is not like that anymore. Many more updates have been added on YouTube.

Similarly, the code of Bitcoin has also received various new updates. Which basically happened through hard fork. There were various errors in the smart contract which led to a possibility of the coin being hacked. As a result, there are new updates in Bitcoin. As a result, cryptocurrency still survives. These updates are mainly done by developers and miners together.

But sometimes new updates are not liked by everyone. As a result they want to trade bitcoins in older versions. And which is basically possible through hard fork. This system is a powerful technology. As a result we are saved from being hacked. Basically all these updates come to make user experience easier.
