If you're interested in securing your cryptocurrencies with a bitcoin wallet, you'll first need to create an account with your desired platform. Most non-custodial wallets (wallets that you hold complete custody over) offer downloadable software that you can use to secure your private key and crypto assets. However, if you're using a hardware wallet, you'll likely need a USB cable to connect to your platform's external storage chip. Once you've created your account, connected the necessary devices or downloaded any required software, you'll be able to transfer over any existing crypto assets.
