I'll list few things just to help everyone here as I believe 95% of the users have no clue how this network works and what they're doing to themselves.
Choose your case and you'll understand the level of your privacy. I won't talk about online exchanges, obviously you gave them all your info so you're not safe-private at all.
When you don't run your own node, third party broadcasts the transactions for you, so they get info from your devices as you're connected to these servers.
XPUB = is basically a master privacy key, anyone who knows it can view all past and future transactions that wallet created or ever will create, even if each transaction used a different address.
Case 1:
I stored my bitcoins into a non-custodian wallet (pc or phone) like Blockchain.info, Exodus, Electrum, Coinomi, Metamask, TrustWallet, LEDGER, TREZOR(AS YOU RUN THEIR APPS) etc etc.
In that case IF you used VPN as you created and as you use these wallets:
Your IP is stored into VPN's server and in case of a court your IP can be found and will be associated with all your BTC addresses.
In that case IF you DIDN'T use VPN as you created and as you use these wallets:
Servers of all these wallets have your IP and know your xpub so pretty much they know you and all your Bitcoin addresses (if they got your mac address they're able to know even more things about you).
Case 2:
I stored my bitcoins into non custodian wallets that support Tor like Samourai wallet, Blockstream Green etc for Phone and Wasabi Wallet for PC.
In that case your Bitcoin addresses are not likely to be associated with you (obviously if you move these coins to an exchange or into another wallet you're back to case 1.
Case 3 (and the best one):
I run my node and connected my wallet with that.
Subcases:
- I connected Wasabi Wallet which supports Tor with my node -> Your ISP knows you run a node but your Bitcoins can't be associated with you.
- I connected a wallet that doesn't support Tor -> Your ISP knows your node and your ISP knows which server stores your Bitcoin addresses which are obviously connected with you.
- I run node over VPN and connected Wasabi -> You're much safer but still the VPN server knows you run a node.
- I run a node over Tor (best way is if your Operating System is Tails) and connected Wasabi (or even if you didn't doesn't matter that much) -> Noone knows that you run a node, noone knows your Bitcoin addresses.
After reading this thread I feel exposed, what could I do?
- Run your own node and run it over Tor.
- Use wallets that support Tor.
- Use Coinjoin (it's a coinmix feature of Wasabi). That doesn't make you 100% safe but it's something that helps A LOT, the more you coinmix the better of course. A chainanalysis can be done but doesn't mean they will be able to find your new btc address 100%, they have to find the owners of other 100-200 addresses which were participants to that coinmix so they can be sure that the new address they found is yours. In case of a court if it's not a criminal case that had to do with millions(many not just 1-2) or even billions of dollars worth of bitcoin I doubt that they'll do such analysis. Also imagine if you do 10 or 20 coinmixes.
If everyone uses CoinJoin chainanalysis will be useless, also exchanges will be forced to accept coins that come from coinjoin as they won't have a choice.
In few years you won't be able to deposit coins that used coinjoin feature in the past to online exchanges. If you want to do it, you'll have to do it now, I dream about a community that often uses schnorr, taproot, ricochet and coinjoin but that would be very ideal as people don't know the basics.
In code we trust, Bitcoin is the future.
