From my understanding, cryptos enable you to do anonymous transactions by hiding your IP during those transactions. However, you're still able to give information about yourself when you're making a payment with crypto for example. Otherwise how could the company who receives the payment check your identity? Then what's behind the concept of "anonymous"?
You're identity is never recorded in the bitcoin protocol itself. So if you make a payment to a company the only record they and you would have is the transaction ID. Unless you blatantly link your wallet address to your real email address or social media accounts, you can stay as pseudo-anonymous as you would want.
