Why are you arguing with someone about something you don't know? That's not very logical now, is it?
Noone can find out who you are with your IP address unless they can contact your ISP and get the info there but that can only happen under a Subpoena or a hacker gains access to the ISP database and even then it's hard to prove who has what IP because IP addresses are dynamically used and cycle often. An IP address is nowhere near enough evidence to prove anything. Otherwise if it were could you imagine the havoc a criminal can cause of they hack into your WIFI outside of your house and go on a crime spree.
I was having an argument with a friend. He says that you can't be anonymous to the bitcoin's network. Both nodes and wallets use, leads to an ip address where information can be found.
I had read in this forum that you can hide it with hardware? How exactly?
No, it is the I.P address that will going to obtain and not your identity. Identity could be obtain when you do KYC and entrusted it to an exchange keeping it as what they promise. However there are.exchanges that has been hijack and some of the users holdings crypto was stolen and being transfer.
Don't get bother with your friend's argument. Just let him think that way for you had known already that being anonymous is one feature that bitcoin platform has from the start and up to this present time.
Did you not read properly? He is wrong and his friend is right.
It's very hard to keep your identity completely hidden. Probably impossible to have it exactly 100%.
There are cameras that could be used to facially recognize you. Your disposable phone, unless it has all antennas removed, will send and receive information from and to the service provider it's been registered to (and even without it, AFAIK, a phone with battery in it could still send and receive information - especially if it's a smartphone, and assuming you're using Bitcoin with it... it most likely is). Just think about it - even without a SIM card you can still call 911, right? Even if you turn your phone to Airplane Mode, do you have any guarantee that it has terminated any communication?
A complete anonymity is just a dream now a days especially if the authorities are targeting you. The speaker in your phone can be activated and if the authorities knows your IMEI number of your mobile they can activate your mobile speaker even if you turned your phone to airplane mode your communications can be captured.
When it comes to bitcoin it is impossible to stay fully anonymous if you are using exchanges because they force us to verify our identity, if you are making money online and if you are accepting it in bitcoin and not using the traditional exchanges it is possible to be anonymous.
Iv'e never heard so much shit in my life.
