Yes but it's not only wallets, that is possible because of transparent blockchain and non fungible by design. Imagine you could get a dollar bill* which value could evaporate and even put you in criminal trouble because X amount of unrelated money transfers before it got to you it was used in something criminal. *dollar bills are also not fully fungible because IDs and currency tracking but those aren't implemented everywhere unlike with btc. Fungibility: gold = monero >>> dollar bill >> bitcoin and most other transparent coins
