Hi, sorry if this may sound like a dumb question - I'm just getting into crypto and I want o make sure I'm doing things the right way.

When creating a new wallet or using a new trading platform - what is the appropriate way to conduct with regards to my own privacy and OPSEC?
Do you enter your actual details (name, address, phone number, etc.) and upload your actual documents (ID, passport, etc.)?

If yes - doesn't that sort of defeat the purpose of anonymity?
If not - does that put you at any sort of risk of losing access to your funds (as in - should you lose access to it they won't be able to verify that it's actually you because no personal details match, just as an example).
