I have some question about monero. I bought some time ago trezor safe 3 and i know most safe way to store crypto is to have them in cold physical wallet, but im not sure if this case is right with monero and if i want to stay anon. I think i bought it from official site but with card or paypal (dont remember now, anyway not anon way). My question is - can they somehow link which trezor wallet i use from payment or order info, or if they have any backdoors,? Or it still will be more secure to use gui or cli wallets like monero.com or feather or cake wallet (with tor or tails)?
