Exchange vs Wallet: Where Should You Keep Your Crypto?

An exchange is where you buy crypto. A wallet is where you keep it. On an exchange such as Coinbase, Binance or Kraken, the company holds the coins and you hold a login, rather like a coat check ticket. In your own wallet, such as MetaMask or a Ledger device, you hold the key itself. The exchange versus wallet question is really one question: who has the key?

What is an exchange account really?

It is a number in a company's private database. The coins you bought sit in the exchange's own wallets, pooled with everyone else's, and your balance is a promise to hand them over when you ask. Most of the time that promise is kept, and the convenience is real: you can pay with a bank card, reset a forgotten password, and get a human on support. But exchanges have frozen withdrawals, been hacked, and in a few cases collapsed with customer coins inside. That is where the old phrase comes from: not your keys, not your coins.

What changes when you use your own wallet?

You become the bank. Your wallet holds the key, and the coins on the public ledger answer only to that key. Nobody can freeze your balance, nobody asks why you are sending money at two in the morning, and no company failure touches you. The trade-off arrives in the same breath. There is no password reset, no support line, and no undo. Your seed phrase, the list of words the wallet gives you at setup, becomes the only backup that exists.

So where should your crypto sit?

A rule most people settle on: keep on an exchange only what you are actively trading or about to spend, and move anything you plan to hold for months into a wallet you control. Match the wallet to the amount too. A phone app is right for pocket money, a hardware device for savings.

If you have never moved coins off an exchange, do it once with a small amount while nothing is at stake. Set up the wallet, write the seed phrase on paper, withdraw twenty dollars' worth, and send it back. The whole exercise costs a fee or two and removes the fear from the day it matters.
