You don't necessarily have to set up your own bitcoin wallet to store your assets. Some crypto exchanges — like Coinbase and CEX.IO — offer their own wallets to users. The difference between these platforms, though, and the bitcoin wallets mentioned above, is mainly one of security and custody. If you'd prefer to have complete custody or control over your money, you'll probably need a non-custodial bitcoin wallet. Unlike most crypto exchanges, these stand-alone wallets give you absolute control and security over your crypto assets. With the crypto exchange wallet, the exchange itself would still have some level of control over your assets.
