I assume by "portfolio," you mean your crypto wallet balance.

If you're using the Binance app, log in to your account and click on Wallet. This will display all your funds on Binance.

Keep in mind that Binance has multiple wallets where your crypto may be stored, such as:

Spot Wallet

Margin Wallet

Futures Wallet, etc.

Your funds in each wallet will be shown separately, while the total balance across all wallets can be found under Overview.
