Dude if you get $100 worth of bitcoin non kyc, it’ll sit in one address. Next month you can get another $100 in bitcoin that will sit in a different address. They are not linked together so no one knows your net worth. The amount will never change. No one knows it belongs to you except the seller and that’s only if the seller knows who you are. You can leave it there for 10 years and nothing will happen to your privacy. Then when you want to spend it, swap for monero.
