Without using any of the tools to obscure internet activity, how are you going to track me in the following situation.
Set up a node using public WiFi, and a copy of the blockchain I've already downloaded.
Receive Bitcoin into that wallet.
Use the Bitcoin to purchase gold coins.
Wipe the hard drive on the computer with the core node.
You speak too scientific a language, it's quite difficult for me. And not just me, most people do not know how to do this. I'm just trying to understand how the blockchain and bitcoin. "Blocks, knots" is difficult for me.
Not all altcoins either. There are some privacy coins that are anonymous. zcash, monero, electroneum. To name a few.
Of course as soon as you try to exchange it to fiat via a centralized exchange all anonymity is lost.
Yes you are right, I did not consider the peculiarities of these coins. For the Monero I heard a long time that it is used to pay on the black market.
But still, any contact with the exchange or Fiat money, you can immediately recognize.
Think of it this way, Ill know the address that someone sent a TX from, but I wont know the inside leg measurement of the sender
If I understand you correctly, you are talking about the situation when me transferred someone bitcoin, and I then transferred to several other accounts, it is impossible to track in the history of transactions? After all, through explorer it is possible to check wallets and transactions with them. Correct me if I misunderstand you.
