I've noticed that when looking for a vendor on P2P Exchanges (which utilise an escrow service) it's possible to select their country of location.

Presumably, provided the vendor has plenty of good feedback, then their country location isn't something of particular concern?

I guess one reason why a purchaser might select upon vendor's country location would be if wanting to meet in person. If that's not happening, I guess their country location shouldn't be of any particular concern; particularly if paying by bank transfer?

Any thoughts? 

I was looking at the sign-up procedure for the four non-KYC peer-to-peer exchanges below:

a) Bisq (BitSquare)
b) Hodl Hodl
c) LocalCoinSwap
d) LocalBitcoins

It would appear that only d) localbitcoins.com asks the following:

1) Enter your first names as they appear on your identity documentation.
2) Enter your last name as it appears on your identity documentation.


If one of the main draws to using such exchanges is to prevent personal data being stolen in the event of a hack, I was wondering what thoughts are on this? Would you just stick to the first three exchanges due to this? 

[one unique address]

If using one of the major brand cold storage hardware wallets to store BTC, does the hardware wallet have one unique address or can it store many different BTC addresses so that purchased BTC could possibly be stored across many different BTC addresses stored on the same cold storage hardware wallet?

I am considering purchasing some BTC using one of the following sites:

a) Bisq (BitSquare)
b) Hodl Hodl
c) LocalCoinSwap
d) LocalBitcoins

I have discovered online that it is possible for persons to send BTC through a mixer and that if this is done, it may cause issues if attempting to later sell via an exchange.

If I purchase via one of the four sites above from a seller, is there any way to determine if the Sats which I purchase have been through a mixer in advance in case this might cause an issue at some later date if I wanted to sell via an exchange or if I wanted to try to obtain interest for stacked sats, which I believe is also possible.

Is this something which should be of concern?
