Coinbase

Coinbase is a custodial exchange, so the honest answer is that its safety has two parts: the company's own security, and the fact that it holds your keys for you. On the company side, Coinbase is a US public company that files audited financials with the SEC, holds customer crypto 1:1, and keeps the large majority of assets in offline cold storage. US-dollar balances are held at FDIC-insured banks, which insures the cash, not any crypto.

What that safety does not cover is your own account. Coinbase has never had its cold storage drained, but individual users are routinely targeted by phishing calls and texts that impersonate Coinbase support. Turning on an authenticator-app or hardware second factor, and treating any unexpected “Coinbase” message as hostile, protects you from the attack Coinbase cannot stop for you.

If you received a text message with a “Coinbase withdrawal code” you did not request, it is a scam, not a Coinbase feature. The message is designed to make you panic and call a number or click a link, where a fake “support agent” walks you through “cancelling” the withdrawal — which in reality hands them your account.

Coinbase does not send unsolicited withdrawal codes by SMS to “confirm” activity you did not start. A real withdrawal you initiate shows up inside the app. The safe response to one of these texts is to ignore the number in it entirely, open the Coinbase app or coinbase.com yourself, and check your account there. Never read a code aloud or type it into a page you reached from a text.

Coinbase runs two fee surfaces. The simple Coinbase app charges a spread plus a flat or percentage fee that is convenient but among the more expensive ways to trade. Coinbase Advanced (the successor to Coinbase Pro) uses a maker-taker schedule that starts near 0.6% taker for small volumes and falls with 30-day volume — far cheaper for anyone trading more than pocket money.

On top of trading fees, moving crypto off Coinbase carries the network fee of the chain you are using, which Coinbase passes through. The practical takeaway: for anything beyond an occasional small buy, use Advanced rather than the simple buy button.

“Coinbase price” is ambiguous, so it is worth separating. The exchange is where you buy crypto; the stock is a share in the parent company, Coinbase Global, which trades on the Nasdaq under COIN and went public by direct listing in April 2021. Owning COIN is a bet on the company's revenue — which rises and falls with trading volumes — not a holding of any cryptocurrency. We do not quote a live COIN share price here; a brokerage or the Nasdaq is the right source for that.
