If your only interaction with cryptocurrencies is buying them through exchanges, it can be difficult to understand concepts like private keys and public addresses because you have limited exposure to them. But given that it’s good practice to have complete control over your cryptocurrency, it’s important to understand what private keys and public addresses are and how they work.
One of the most common strategies people use to learn is through association. Comparing a new topic or idea to something you are already familiar with can make it more relevant and provide a framework for understanding its logic.
You can use this method when you are trying to explain the concept of encryption keys and addresses to someone unfamiliar with the subject, by relating them to keys and addresses they are familiar with; related to their physicist.
