When you own Bitcoin, what really matters is the ownership and the security of your coins. What counts is the key that unlocks the access to your crypto fortune: your private key. The person who has access to this key really owns the associated coins and can do whatever they want with them.
When you buy crypto online, on an exchange for instance, you are not in control of this key, the exchange is.
A Bitcoin wallet helps you protect and control your private key. Ledger hardware wallet, combined with our application Ledger Live, is the most popular way to secure your funds while giving you the freedom to manage everything on your own. You can send, receive, buy, sell your Bitcoins without compromising their security.
