If you dont use them and just buy to hold or resell it dont matters. You can stay with surveillance coins. If you plan to use them, then Monero s a must. So merchant where you will spend them cant see how much money you have and where you got it and what else you bought. Not to mention that Monero you hold have no history. No one will know if maybe in past Pope Francis had it or Qasem Soleimani or Luka Dončić. No info attached at all.
