Hello,
If I buy online a Hardware wallet to store BTC, and then put some BTC that I own on it, will it be possible to anybody know that the wallet address of this wallet is mine.
This is assuming the BTC provenance is not in anyway connected to myself.
Thanks
Technically speaking if the seller had access to the hardware beforehand and they were able to see the wallets they made then they would be able to record the addresses (and then link them to you) if they wanted to, however it is not likely they'll do something like that, but you never know for a fact.
If you print your own wallet then there is no real way to link anything and you should be gucci.
