It’s a great question, without a great answer lol
WoS only requires your email to back it up, but there’s no reason you couldn’t spin up a side email (ideally at protonmail) to use just for that. And honestly I’m not sure how much info any of these apps learn by default when you download them from the App Store.
Ultimately, KYC isn’t all or nothing. In the most serious circumstance, it’s an entity having all of your identifying info and associating it with every Bitcoin purchase/transaction you make.
An email or a debit card number is identifiable, but doesn’t result in the same honeypot of hackable personal data.
I like the “separate side by side stacks” model. Two separate wallets, two separate sets of addresses. One is KYC’d and bought on an exchange, using spot purchases, easy DCA, and limit orders. Usually this is someone’s first stack.
Then a separate one, purchased privately peer to peer.
Tagging in #[4] whom I believe has some great resources on this topic, but I can’t find them at the moment
