A crypto wallet does not actually hold your coins inside it, the way a physical wallet holds cash. Instead, it stores your private keys, which are the secret codes that prove ownership of coins recorded on the blockchain. Whoever holds the private key controls the coins, which is why protecting that key is the single most important habit in crypto.
There are two broad categories: software wallets (apps on your phone or computer) and hardware wallets (small physical devices that keep your keys offline). Software wallets are convenient for everyday use, while hardware wallets are safer for holding larger amounts long-term because they are much harder for hackers to reach remotely.
When you set up a wallet for the first time, you will be given a seed phrase, usually 12 or 24 words. This phrase can restore your entire wallet on a new device, so it is effectively the master key. Never type it into a website, never photograph it, and never share it with anyone claiming to be support staff.
