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?
Very simple, you can use various VPN programs that change your IP to another one. There is also software that makes your IP dynamic, i.e. it is constantly changing with each new visit to the Internet. Accordingly, the wallet will not be linked to a single address and you will be completely anonymous.
