Cryptocurrency has become a popular way to store and transfer money online . People like it because it’s faster, borderline, and gives them more control over their funds. However, as banks can be robbed or credit cards stolen, cryptocurrency also has risks. The most common places where there are risks are crypto wallets and crypto exchanges.
In this article, we will explain what these risks are, what difference they make, and how users can be protected. The goal is to make this explanation simple enough that even a 7-8 year old can understand the main ideas.
1. What is a crypto wallet?
A crypto wallet is like a digital wallet or pocket where you hold your cryptocurrency. Unlike a real wallet, though, it’s online or stored in a computer file.

Cold wallets: These are offline like USB devices. They are difficult to hack but less convenient for everyday use.
Think of it this way:
A warm wallet is like keeping your money in your pocket-it’s easy to reach but can be stolen.
A cool wallet is like keeping your money safe locked in the house-it’s safer, but you can’t spend it fast.
