To me is that it can be anonymous. That if you just don't want certain entities not to know how much money you have, you can have it on a piece of paper, or in your computer.
but what if they will search your name or your bitcoin address on a bitcoin explorer ? they can still see your balances and transaction because bitcoin is not that anonymous . if you want real anonimity then go on private coins like monero . by the way , the most valueable benefit that bitcoin gave me is profit because i use my bitcoins as an investment tool and i can earn regular profits with it but aside from that , i also use my bitcoin as a payment method when i need to gave money for my family as they also have a bitcoin wallets installed on thier phone and they are far away from me .
