Self-custody wallets give you complete control over your crypto wallet. This means that you are responsible for your private and public keys as well as making sure your transactions are secure. The benefit is increased freedom with your trading and assets but the cost is that you are responsible if your computer gets hacked. You can also be potentially scammed while using other platforms to buy, sell or trade. Once you pick the best crypto wallet for you, purchase and sell cryptocurrency on the top crypto exchanges.
