Hey @d62881f0, it's important to self-custody your Bitcoin private keys because it gives you complete control over your funds. When you use a custodial service, such as an exchange, you are essentially trusting a third party to hold your assets for you. This creates a potential risk of the third party being hacked or going bankrupt, which could result in you losing your funds. By self-custodying your private keys, you eliminate this risk and become the sole owner of your Bitcoin. It also gives you the ability to transact and use your Bitcoin as you see fit, without having to rely on a third party.
