Ethereum

In my Coinbase Wallet it shows this X amount bellow "cripto", but I still have 0.00 dollars to use.

Jesus OP. I hope you meant to write crypto, and aren't out here installing 'cripto wallets' on your devices.

For starters Etherscan is a historical node who keeps a copy of the Ethereum blockchain, and generously displays it online for public use. They are not an authority in any matter whatsoever. They will never reach out to you for any reason, especially noting that you have never given them your contact information to begin with.

Obviously this email is a scam. But underlying it, that means your name and email and crypto interests are being sold on malicious scam-lists someplace. It's very wise to burn that email and never use it again, and to be more proactive with your data going forwards. These scams can get very convincing, especially now AI has run amok, please don't make yourself a target.

This post makes you a target also FYI. Ignore any direct messages, or messages in private. People may reach out and offer to "help' you in any way for any money or information in return, now that you've told us all publically this weak 'cripto' scam almost worked on you.

Tether USD or USDT isn't the same as dollars either. It should show as 'USDT tokens' in your wallet, you may need to add a token manually before it becomes visible. You can search your public wallet address (your deposit address) in Etherscan's search bar and it will show you all the assets you hold. If you don't hold any USDT your wallet (check ERC20, check internal transactions, check all the tabs on Etherscan) then your wallet may in fact be burned also.

Edit: you can check if your email is on those lists here, https://haveibeenpwned.com/ -- if yes (it will be yes in this case), time for a new email. It will show which leak got you too, eg the Ledger user database leak, and how bad it is.
