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?
As long as you don't connect your bank account or personal info on the address, you can easily hide your identity with Bitcoin simply by using TOR to mask your IP. If you want to cash out, you can also use TOR plus mixers.
