Yes. Most of the mainstream apps do. Not a big deal unless you’re buying/selling thousands all the time. If you’re wanting to remain completely anonymous I would recommend a bitcoin atm if you live in a major city and pay cash and use an anonymous email. I don’t think think it’s necessary if you are just sending small amounts every month or two. Don’t send from cashapp directly to a source. Use a secondary wallet to send cash app to and then send that to a source. Extra fees but you won’t get your account shut down.
