When it comes to earning any type of profitable goods, whether it's digital or physical we need a wallet to hold our earnings of course! There are a few different kinds of wallets you can have when it comes to Crypto. You can have a mobile wallet, a web wallet (which this seems to be the most popular one with Coinbase being one of the top wallets), hardware wallet, Desktop wallet, and in very rare cases sometimes people will use Physical Media such as a QR code. They've all got their own pros and cons, the one pro for physical media wallets is that they're not easy to be hacked but if it's on a QR code you'd have to keep in stored in a safe, dry space. Hardware Wallets are ones that are usually on USB drives, which is great if you know where it's at 100% of the time and you don't lose it or damage it. (So in somewhat of a way, it's similar to Physical Wallets.) Desktop Wallets, as the name implies are a program that contains your private keys on your computer. I still have yet to invest in Crypto so I don't currently have a wallet, but I'd probably just start with a Web Wallet and use Coinbase.
