Let's say you have a large amount of BTC and you want to spend it / invest it / transform it in fiat but you do not want the BTC to be traced to exchanges or to you, how would you do it ?
It's not for me, it's to further my understanding of the space.
The only way that you can withdraw cryptocurrency and not get traced is through P2P method.
Any other method of transaction apart from that is going to leave traces online and anyone will be able to trace you easily.
Although a lot of people don’t bother about that, that’s why they are making use of centralized exchanges.
People only try to hide their identity for a reason, maybe when they are living in a country where Bitcoin is not legal.
If Bitcoin or cryptocurrencies (in general) are not legal in your country then there is no other way to buy and sell them if not through P2P.
